Honestly, there was indeed a debate about whether to include this phrase long associated with the Blackwing on our new pencil. Many Blackwing fans seem to feel quite strongly that this slogan should have been used and do associate this slogan directly with the pencils smooth writing performance. One person even referred to our new Palomino Blackwing version using the phrase “One Quarter the Pressure, Twice the Speed” to indicate that, in his opinion, it was smoother than the original.

I have nothing against a good marketing and promotional slogan and I certainly recognized beforehand that “Half the Pressure, Twice the Speed” is loved and well respected. However, I’ll admit I never really understood the logic of this slogan from a purely technical standpoint. Increasing downward writing pressure quite obviously increases friction and thus would slow down the gliding of the pencil across the paper with a given amount of lateral force. The inverse is true as well, reducing pressure increases speed. Thus when applied to downward writing forces this slogan is essentially true regardless of the quality of the graphite and how smooth it is in relation to the graphite cores of other pencils. Alternatively, looking at varying degrees of lateral pressure being applied with a fixed amount of downward force, as smoothness increases the same lateral force certainly would increase speed and I can see the logic that reduced lateral pressure might maintain the same speed, but not necessarily double it. Who can write or draw legibly twice as fast anyway? So it did not strike me as a particularly appropriate slogan when evaluated purely from an scientific, literal standpoint to represent comparative performance advantage versus other pencils or even just smoothness in general.
There are indeed testing devices to measure lead wear rates and lay down samples on pencils as well as ink flow rate on pens. I’ve checked with our lead supplier and there is however no current instrument they use to technically measure smoothness under controlled circumstances, just the experience of their trained staff. Presumably if a proper technical definition of smoothness was determined this could perhaps be evaluated by designing appropriate scientific method and test equipment to statistically measure and demonstrate smoothness performance. (Note: Our CalCedar Research department once developed equipment and conducted a set of studies to scientifically and objectively measure the different forces required to sharpen pencils made of different wood species with different sharpening tools. Being a specialist in wood processing technology and supplier of wood to the pencil industry this makes some sense for us to have pursued this, however we are not a specialist producer of our own graphite cores and have not really considered such tests in developing our new Palomino Blackwing pencil. Remember Adam Smith’s Invisible hand.)
Obviously this is a very theoretical discussion for what really ultimately has more to do with consumer perceptions. I doubt Eberhard Faber ever conducted any studies to scientifically measure and demonstrate smoothness before coining the slogan. Looking up the word “smooth” in the dictionary yields several appropriate synonyms which have been applied to the Blackwing Pencil at times “soft”, “silky”, “velvety” and “effortless” being among the most common. From the concept being portrayed that the Blackwing pencil is more effortless to write with, then the idea that reducing pressure corresponds to a dramatically increased speed may be interpreted that the pencil has characteristics that defy natural forces thus imparting a super-natural type quality. Perhaps this is closer to the originally intended meaning and interpretation for this phrase than my more literal view expressed above, it’s certainly a romantic one. In any event I have no idea who to credit for the inspiration and genesis of the “Half the Pressure, Twice the Speed” slogan. Perhaps it was simply the Mad Men. Who knows?
From a trademark perspective it does not appear that Eberhard Faber ever took action that we could find to protect this phrase. During our cursory evaluation of this topic with counsel we came to no conclusive answer whether it would be worth the effort and expense and if it would ultimately successful in being granted a trademark. Certainly we could have used it without taking such steps but for this and other reasons chose not to.
We did consider alternate slogans that I felt would more directly reflect the Blackwing’s smooth writing performance and would also improve linkage with some of the existing “slogans” related to the Palomino’s performance. (e.g. Ride the Palomino, the smoothest ride around. Or alternately, Smooooth…!, which came from one of our fans in an animation about the Palomino). We’ve also since had several suggestions including some of my favorites: Fast as Light, Dark as Night and Back in Black. Ultimately we rejected printing any slogan as a matter of the economics of dual side printing, and a desire not to offend those who may not like a changed slogan and also consideration for trademark concerns.
As we look ahead to future production the decision of whether to use the “Half the Pressure, Twice the Speed” slogan is currently under re-evaluation though perhaps alternately we should just hold a proper contest for a great new slogan unique to the new Palomino Blackwing and a new generation of pencil fans. Once concept now under consideration is to produce a separate SKU as a classic reproduction version, though when or whether we could support multiple Blackwing items in the line over time really has to be seen with how sales go as we move through the fall. We are now working on last few details before putting up the new Palomino Blackwing for sale on Pencils.com.

Ultimately, as we all now understand the story, the breakdown of the specialized ferrule production equipment and the costs to repair or replace the machine factored in the decision by Newell Rubbermaid (Sanford) to discontinue the Blackwing. The economic return did not seem to cover the cost of restarting production given the limited sales for the product and the company’s primary focus on mass market products. Of course, I also doubt anyone ever expected pencil aficionados would eventually be willing to pay from $20 to $40 each for these pencils down the road either. It’s an interesting speculation to consider if armed with such knowledge what new pricing they might have been sufficient to justify the repair or replacement of the machine and continue the product at that time. Who knows if anyone performed such an analysis or just looked at the unit volume and decided to call it quits?

Bringing back the classic ferrule with its flat rectangular, extendable eraser was a key factor for me in deciding to move forward with the Palomino Blackwing. As some fans have noted the Palomino, Mitsubishi Hi-Uni, Tombow Mono, or Staedtler Lumograph brands each have specific grades that compare rather closely to the original 602 performance. Therefore at least to me, without this classic ferrule and eraser design included there could be no return for the Blackwing brand. Finding a vendor that would agree to reproduce the functional eraser assembly to our desired quality standard while protecting our tooling investment and not allowing reproduction for other pencil manufacturers was important to me. Another key decision factor was to obtain a reasonable economic cost relative to standard tipping, even though it was clearly always going to be much more expensive per pencil than regular erasers. Important considerations became the tooling costs investment to be able to produce the assembly components as well as the appropriate minimum order volumes for a given unit cost. Discussions and investigations on this actually took place over a period of a year or more. We did commit however to the tooling cost early on to produce the ferrule (well over a year ago) just so that we could begin to produce some test samples. At one point after we had paid for the tooling we we’re told we would have to move our original target minimum order size for our first order from 50,000 as originally quoted to 500,000 pieces if we wanted to keep the price unchanged. This just about killed the whole project and created long delays as we assessed whether to proceed or not, considered alternate options and negotiated further. By the standards of most commodity oriented good quality, high volume cedar pencils (e.g. Ticonderoga or Mirado) selling at or around $0.20 to $0.25 each 500,000 pieces is not a very high production figure at all. However, for a niche, high quality item we expected would ultimately have a retail price point, somewhere between $1.50 to $2.00 per pencil, this could be a significant initial inventory investment just for these assemblies, depending on ultimate acceptance of the product. This also raised concerns such as eraser life if initial sell through was not very good. In the end we were able to settle on an initial production run of 100,000 ferrule/eraser assemblies and this coincides with the number of pencils we are producing in this first run for the Palomino Blackwing. Feedback on the eraser assembly and performance overall has been positive overall. Several reviewers have noted the exceptional care with which the ferrules and erasers are glued, rather than crimped on to the pencil mechanically, and that the flat side of the ferrule/eraser set is oriented so that the imprint is face up. This is not the case with the original Blackwing which has random application angles. In reality the end of each pencil is actually machined down slightly before attaching the eraser assembly vs. standard eraser tipping which more commonly slightly crushes the wood before attatching and crimping on the ferrule and eraser.

The Palomino Blackwing erasers are about 25% larger in total cubic volume and 15% wider than those of the original, providing improved eraser surface area. They are also produced with improved materials than the natural rubber/pumice composite materials used in the original Blackwing’s erasers. Here I’d like to add a technical note as there have been several comments on blogs referring to the Palomino Blackwing’s eraser as a vinyl eraser. This is not the case and is an inaccurate assumption on the part of those individuals. While vinyl based materials did become more prevalent for art and pencil top eraser use as a replacement for traditional natural rubber based composites, vinyl erasers are actually currently in declining use by the industry. Our erasers are produced using Thermoplastic elastomere (TPE). Thus they are more appropriately called polymer erasers vs. vinyl erasers which are produced using PVC material. The change to TPE from PVC was initiated by the industry to eliminate chloride from the production process and finished product. The vinyl erasers that are most commonly used today are larger hand held block eraser formats. Most pencil top erasers from major brand manufacturers and all those we use in our California Republic product ranges are polymer erasers, even if they are other colors such as more traditional red or pink. For an interesting history of the eraser and technical information about the different materials used over time Staedtler has a very useful resource guide, here.We did get some feedback that with our darker lead mark than the original Blackwing, erasing with our new eraser still leaves a slight trace of a smudge, or “ghosting”. This is another issue we are re-evaluating for future production and are now told by our supplier there is an opportunity to improve on this versus the current eraser we are using in the Palomino Blackwing. However, we have not had a chance to evaluate cost differences or do any actual testing. The current eraser is the same quality as that used on our Palomino HB pencils.Finally, some traditional fans do seem to prefer the old pink eraser color versus the white version which we selected. Others have suggested black would be very nice as well. Color of the eraser specifically is not really a factor in it’s performance though it seems to be a common misconception that a white eraser works better than a red or pink eraser. It all comes down to materials. Performance differences with the original Blackwing certainly have something also to do with the age of these older pencils and the effects of oxidation and exposure to light. At this point I cannot indicate if there will be an eraser color change down the road as this is dependent upon what future cosmetic design changes we might implement for the pencil overall as well.

This feature set was considered the fourth most important across our six features ranked by our test groups.

Here there is a clear allegiance among traditional Blackwing fans to the historic charcoal or graphite gray gloss finish and imprinting information on the pencil to more closely match that of the original product. Many participants readily admitted technical and overall usage performance is the most important factor, but given a preference they’d go with a finish treatment close to the original 602. Some commented that the Blackwing font itself is different than the original. We did initially try to match exactly the original Blackwing font. During our detailed research on this topic we could not find an exact match, but we learned that it was a variation of a very old German font, which makes sense given the heritage of Eberhard Faber. We selected a more updated font that matched as close as possible without going to more expensive and time consuming efforts to have a designer create an exact match. Additionally, there have been quite a few suggestions to increase the size of the Blackwing name relative to Palomino to make it more characteristic of our treatment of the Palomino brand relative to California Republic brand on our Palomino pencils. The relative font size is a valid point and probably will be corrected in future production pending assessment of some related technical and marketing factors as we consider potential redesign.My personal view in designing the new Palomino Blackwing pencil has been that a product named Blackwing logically should be finished in black. As mentioned in an earlier post I generally agreed with finish recommendations suggested in that Frankenpencil post and this to some extent guided thinking on this design, though admittedly Lisa was not talking about a new Blackwing pencil, but her ideal “Frankenpencil”. In any event it seemed there was quite a lot of interesting and supportive discussion around this post and with some of these design characteristics so it seemed appropriate to incorporate some of these into our design. The addition of the gold band was simply to keep some added Palomino brand family connection in our pencil range design. Some people have commented they feel the gold band is too much of a departure from the original.

So having decided on a black finish our next choice was whether to go with a higher gloss look more typical of our standard Palominos or alternately a matt finish to provide some further differentiation for this new unique product within our existing Palomino range. The first test samples of each looked excellent and very reflective of our Palomino quality regardless of glossy or matt finish. Ultimately, I chose the matt finish as I wanted some added distinctiveness for the Blackwing vs. the standard Palomino graphite range and some differentiation from the Tombow Mono which is already finished in glossy black. (Despite this we still received a couple comments comparing our new pencil to the Tombow Mono finish which I’ve shown side by side in a photo here.)
Unfortunately, once the initial production began and we later received a couple hundred samples we noticed some very faint foil speckling occurred during imprinting and these tiny foil flakes had been sealed in when the sealer coat was applied. This covering quote was originally intended to protect the foil imprint and band from any further wear from continuous handling during use as is occasionally noted with respect to many pencils. It’s not a process we do with our existing Palomino products and probably should be eliminated for future production. Though we felt the pencils looked very good overall we were not fully satisfied with this characteristic as compared to the samples we approved before initial production. I actually stopped eraser tipping production on the balance of the pencils, but by this time all of the initial production pencils had been imprinted and sealed. My concern was do we release “as is” or not and it was at this time I determined to do a consumer sampling and evaluation to get a gauge on this issue. Among our options was scrapping the initial production and going back to design table before actually launching the product as well as evaluating other potential fixes. I determined this process would be a good opportunity to get broader evaluation of the product for ideas we could incorporate if we ended up doing a complete re-start or to be used for future design modifications if we ended up launching “as is”. After three weeks of feedback, we have now determined to proceed with the launch of the product “as is”. There were several decision factors, the first and most important being the overall positive response we’re now seeing to the Blackwing Palomino when considered across all of our evaluation groups. Despite a clear preference by many traditional fans for a more classic design and some indications the finish quality is just not quite up to par with Palomino, it appears we have developing demand now with people pressing us for pre-orders regardless of finishing characteristics and we learned that these characteristics consistently did not rate as highly on the scale of importance vs. other product features. Another major factor was that we subsequently determined that going back to the drawing board on design would result in a more extensive production and launch delay than originally anticipated, probably until mid to late 1st quarter 2011. This relates to scheduling issues with our subcontractor as well as to allowing adequate time to address the redesign process, including potential fine tuning of the graphite core formulation. Of course the cost of scrapping or reworking any of these pencils into other products from the initial run if possible was also a relevant decision factor, but not the first priority. I was fully prepared to scrap if I felt this was absolutely the best decision going forward and I’ll stress that our final decision was not self-evident at the point we began the evaluation process.As previously mentioned we are now moving forward with expediting market availability of the new Palomino Blackwing from our initial run. We expect to have more definitive information next week on pricing and order availability. In the meantime we also have a breif update to our Coming Soon page.

Overall, in our Palomino Blackwing bench test graphite smoothness and graphite wear came out as the first and third most important features of the six specific product features our survey groups were asked to prioritize. The second most important item was considered to be the overall performance of the pencil as a whole. We did not list graphite hardness or darkness as performance features to be rated since these are generally related to wear rate. We did get specific qualitative comments and feedback related to hardness and darkness which we have evaluated as part of this assessment.
Realistically, as much as we all like seeing those images of writing, sketching, and shading and cross hatch gradations, etc. on all these blogs reviews these only serve a limited visual purpose. They do not technically demonstrate smoothness of the core as much as variations in darkness and overall density of graphite mark. They are simply a record providing evidence of a process of personal evaluation.

Perhaps if enlarged enough one might notice respective comparable differences and gradations of fineness in the consistency of graphite material being deposited throughout a stroke across the paper. As my high resolution digital SLR camera was stolen recently and my replacement not yet arrived we’re just using some simple images in this post, others have already well documented their own experimentations. As I’ll discuss a bit further in a few days when we cover the topic of “Half the Pressure, Twice the Speed” we are not aware of any objective, scientific test equipment used in the industry today for measuring “smoothness” of graphite writing cores. So when it comes to smoothness we must rely on the more subjective experience of our test group, our own personal comparisons and the experience of our supplier.

Our control group of experienced Blackwing 602 and other pencil users provided a broad range of feedback on this topic as would be expected. Every individual experiences the tactile and sensory act of writing and drawing with a pencil through their own unique perspective; writing pressure, hand and point positioning vary and is not always consistent even by the same person or differing uses such as drawing and sketching vs. writing. Comments posted on Lexikaliker even mention differences in point angles used for writing in different languages or alphabets . Additionally, variations in the graphite cores of original 602s from different production periods mean some respondents had different reference points for the original Blackwing’s performance. Older Blackwing production dating back to the 1930s exhibit softer-darker cores and more recent stock produced up through and into the 1990s are generally harder with a lighter mark. Unsurprisingly, the range of test group scores on graphite smoothness had the highest deviation of any feature rated. This clearly reflects the higher level of subjective feel and preference to this topic from user to user.

Overall response from both traditional fans and others in our testing groups has been that the new Palomino Blackwing core is as smooth, or smoother than the original and a bit darker. Although some few do feel it’s not as smooth as the original referencing a slight tendency to a crumbly or chalky, carbon pencil like feel. Most everyone felt the wear rate of the new Palomino Blackwing was faster than the original requiring more frequent sharpening making it perhaps less appropriate for writing vs. sketching, drawing, doing puzzles, music scoring or simple note taking. Some also mentioned higher smudginess of our new product as a concern. A few respondents suggested that our HB was a closer match to the original on the hardness-wear rate dimension of performance. Personally when I do extensive writing and note taking in graphite pencil I prefer our Palomino H grade, even to our HB for that specific purpose. Note that Japanese produced cores by comparison have always been softer throughout the HB scale rating vs. European or US production as the Japanese just prefer a softer core overall.Here is a representative cross section of the qualitative responses from our survey responses good and bad alike. As you can see this reflects a range of impressions we have experienced.“The core is only very subtly different – with the original Blackwing feeling just a touch smoother and just a little less smudgy.”“It actually improves on the lead, which I would not have thought possible.”“The lead is of exquisite smoothness, surpassing that of the original Blackwing. It is quite simply the best lead I have ever tried.”“I pulled out all my favorite pencils (including the 602) and as it is now, The Palomino Blackwing is one of them. Maybe number 2… I would sacrifice a touch of smoothness for a little better graphite wear.”“This core is really amazing. It’s as dark and smooth as a gel pen!”“The point is not as break resistant, crumbles more and wears down much faster, making the pencil less usable for prolonged writing”“Writing with the new Blackwing is a pleasure. The lead is soft and smooth and doesn’t smear, though now and then a tiny crumb breaks off. The new Blackwing’s point wears more quickly than that of the old Blackwing, and the new pencil’s line is noticeably darker.”
We also received some questions regarding whether or not we acquired the original formulation and if not why not produce an exact match for the original graphite core down to every last performance detail. Let me state that we have not purchased any technical knowhow associated with the original product specifically including the formulation for the graphite core. The Blackwing has not been produced now in about 12 years. The Lewisburg factory which last produced these cores and finished Blackwing 602 pencils was closed a year ago and production relocated to Newell’s Mexicali facilities. Additionally, our experience is that there has been a high level of turnover in company management and technical personnel over the past 15 years as new acquisitions were integrated, product lines and manufacturing rationalized, successive cost reduction programs implemented, etc. Quite often the most knowledgeable person with respect to production of items such as graphite cores is the actual worker on the production floor. Here formulations may be adjusted based on variations in inbound raw material quality and specific equipment used according to specific knowledge of those floor workers to maintain product within a specified quality range. Given the changes in that company over more than a decade it’s not clear such knowledge and equipment setup at Newell currently exists to perfectly duplicate the original Blackwing lead. Perhaps there may indeed even be a file cabinet somewhere with the specific product formulation; even so it’s unlikely we could have purchased this.So why didn’t we exactly duplicate the formula through reverse engineering with our very experienced supplier in Japan? This is a reasonable question. However, not a simple and inexpensive process, particularly for a product that was traditionally a low volume niche item. The last producer ceased production partially because a machine simply broke. Returning an investment on a niche item becomes an increasing challenge as total development costs increase. While designing our new product, in choosing between “smoothness” comparability vs. “darkness and wear”, I have always believed that smoothness matters the most in matching the Blackwing. Also, as the Blackwing was a traditional favorite of animators and illustrators – where a nice smooth and dark mark is important to these users – I felt best to err on the side of smoothness and softness of feel over an exact hardness & wear match. So in the end we’ve chosen a close match to the original given the higher weighting we put on “smoothness” and also considered where this particular core would fit in relation to our existing Palomino graphite grades. Our overall consumer feedback supports that we have a high performing product reminiscent of the extremely smooth writing performance of both the original Blackwing 602 and comparable to our Palomino quality range. In conclusion, there seems to be some general feeling that if we can improve on the wear rate while maintaining the current smoothness that would result in an ideal lead, though clearly we have received high praise for the product as it now is as well. It’s not clear to me if the mark on paper being darker for some people is a specific criticism or simply a byproduct of a slightly softer lead. Despite the technical and cost challenges I’ve just noted, we’ve already taken some initial steps to investigate possible modifications to address hardness and wear without compromising smoothness to see if we can get to a more exact match to the Original. Indeed, we’ve begun preliminary testing with our supplier on another formulation that could be promissing. We have not received pricing information and no decisions or very thorough technical evaluations have been completed at this point in time. We will have to keep you all posted on this matter as this develops.
