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.

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.
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.
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.
