    This a long-coming review of a knife that I picked up last year. However, it takes a few months of living with a knife for me to really feel like it’s mine and that I know and understand it. So, I took my time with the review to make sure that I could really do it justice. I broke the review up into sections and gave each a score out of 10, but I didn’t total them up, because I feel like it’s very difficult to properly weight each section in importance and it would be more math than I feel like doing just to end up with a number than wouldn’t necessarily translate to anyone else.

    1) Over-all Fit & Finish and Build Quality. 10/10

    As you can see in the above specs, there is no question that premium materials where used in both the blade and handle. However, what isn’t full represented in the specs are the breathtaking precession, care, and craftsmanship that where used to turn the materials into a knife. The finish and build quality of this knife goes beyond a simple lack of defects, and reaches into that next level that instantly tells you “this is something special” when it’s in your hands.
    Will’s out-of-the-box edge was as sharp as any edge that I’ve ever felt. It was a highly polished edge that was not totally toothless, but was obviously done to show ultimate sharpness, not bite. It’s clear that he really enjoys sharpening and wanted to show what his steel was capable of. It sure got my attention.

    2) Blade: 10/10


    “Feather” is one of my favorite damascus patterns and Will’s 6000 layer version is the featheryest of the the feather patterns that I’ve seen. Often times forge-welded, folded patterns are kept to just a few hundred layers because more layers would be too fine to show good contrast and variety in the design. However, the effect created by the high layer count and Will’s pattern is really unique and beautiful and very appropriate in it’s application. He lined the center or “spine” of the pattern up vey well with the center of the blade so it really looks like a metallic feather from some type of mythical raptor. The pattern also has a very liquid kinetic quality so it also kind of reminds me of the rippled surface of very shallow flowing water.

    According to Will, his design philosophy for the function of this blade was to make something that capable of getting very sharp, but would have excellent resistance to chipping as well as be very easy to maintain. This is shown in his choice of steels and heat treating. Both 1085 and 15n20 are simple carbon steels, and fairly similar aside from 15n20’s nickle content (which adds contrast to the pattern). 1085 is described by zknives as “a high carbon spring steel” and 15n20 is a bandsaw blade steel, that, if I’m correct, is very similar to the L6 steel that is also often favored by sword makers for it’s toughness and ability to take some serious abuse. In a culture where high hardness seems to be king, I really respect and appreciate Will’s decision to temper to “just” 58-60hrc and trade a couple points of rockwell for extreme damage resistance and easy touch-up /sharpenability. This is far and away the easiest edge to maintain that I own. Maintenance-free edge retention is decent, but noting extraordinary like some of the fancy PM steels or ultra-high tempered Japanese steel that I’ve used, but it is amazing how long an edge that seems dead can be brought back to life with just a kiss of a smooth steel hone or quick strop on leather. The result is that I end up putting this blade to the stones less often than I do some much harder steels with which some might consider to have better edge retention.
    When the edge finally does wear to the point that it needs a visit with the stones, I seldom have to go below one of my high-grit J-nat finishers. The steel cuts quickly and easily, but It doesn’t have the mushy, sticky, “stale gum” feel on the stones the some soft German steels seem to have. I also have not had a major problem de-burring and the stropping on diamond charged leather is very rewarding because of how quickly the steel gets insanely sharp, but it have found that I need to use some restraint on the strops because the steel is fairly easy to over-polish.

    Handle 10/10






    Folks with smaller hands or more traditional tastes would probably rate the handle much differently because it’s a BIG‘un. It’s the largest knife handle that I’ve ever held and putting it on a 242mm Suji was another bold and gutsy move, but I’m really glad that Will did it. The handle is actually shockingly light weight and does not make the knife handle heavy at all. I’m guessing that the weight was actually carefully calculated based on the fact that there is a solid aluminum dowel in it’s core. I find that it actually balances the blade very well both in fell and appearance. It tapers very well and I find it to be very comfortable and to offer great control. The finish on the wood is neither high-gloss or matte and it has a really cool kinda “stealth” figuring to it that is only fully seen from certain angles / light which I think matches with the aesthetic of the blade well.

    Performance 8/10

    Will maintained the same design philosophy of strength and durability in how he shaped and profiled the blade and ground the bevels. The convex grind, delayed distal taper, and delayed drop to the point all result in a blade that feels very light in the hand and looks very thin, but is incredibly rigid for it’s stature. It really is like a steel feather. I have never been a laser fetishist or cheered that heroin-chic blade ascetic, but after a few months with this knife, I did find myself wishing that it cut with just a tad less resistance. If you look that the original thread on this knife (link at top) you will see that will actually crafted this knife with a much more bulbous nose and then later gave it a “nose job” which resulted in a schnoz that might have sacrificed a little in the invincibility department, but gained a lot when it comes to performance. I eventually decided to do the same thing with the relatively thick and steep convex section behind the edge. So far I have only lowered the primary edge bevel just a couple degrees and thinned the area behind the edge by just a few microns, but there has been a noticeable improvement / reduction of cutting effort. The blade is still very robust and the combination of gind and narrow width means that sticking is a non-issue.
    As for the profile, I have mixed feelings: Over-all the angle from heel to tip is adequate and provides enough knuckle clearance at the handle. I also appreciate the long, mostly dead-flat section of the blade, but I would be willing to sacrifice some of it in exchange for a more gradual, sweeping belly and transition to the tip. I also prefer a longer, flatter angled “sweet spot” out near the tip.

    Summary:


    This knife is a stunning and masterful piece of art and craft when judged on any scale, but it’s absolutely mind-blowing to think that this was one of Will’s early works and done while he was still a hobbyist maker. It’s a very proficient protein-slicer, the tip sails though onion and the flat profile chops and dices well. The thin, narrow, yet robust blade makes it a natural for the though jobs that you might not normally think a suji could handle (it destroys butternut squash). It’s without a double the best bargain I have ever found and probably will ever find in the knife world. I actually felt guilty paying less than $400 for this knife, but I understand that at the time Will was still getting started in the kitchen knife world and building his
    reputation. This knife paints an interesting picture of it’s maker: it shows someone with a clear mastery of forging and shaping steel and wood and a very advanced understanding of the subtle details that make or break a kitchen knife, but who is also brave enough to make some pretty bold and unconventional design decisions. Will’s passion for this work shows loud and clear. He was great to correspond with and he included 1.5 pages of typed details about this knife, his finishing and sharpening process, and it’s maintenance and care. There was also an additional hand-written thank-you. The note reminded me of a parent dropping their baby off for the first day of pre-school and reinforced the care that he puts into his work. I am honored to have this knife in my collection and plan to add a sibling (sooner rather than later, so I get the order in before his prices and wait list start to reflect the quality of his work

    I hope that this review was informative or at least interesting. Organizing and writing a review on something a deceptively complex as a high-end kitchen knife is not easy and I’m still kinda figuring it out. Thanks for reading and I’d really appreciate any comments or feedback.

    That last pic really shows the Damascus beautifully, one of the best damascuses I've seen. You truly did make the bargain of a lifetime with that one a true work of art.

    Thanks for the review. I also have Will on my radar. Personally, I'd like to see him make a few top notch gyutos before I pencil him in to my top maker's club but I'm convinced he's well on his way.
