Backstory: Some months ago I posted a gyutohiki discussion thread. That led to a dive into lower heel knives. Around the same time I participated in Matt’s PA of a Sab-profile knife. I picked up a vintage Sab, read up on the original KS, and then Doi and Mizuno. Decided that I absolutely needed to try the profile in a 250-260mm sub 50mm knife. After posting a WTB, a very kind long time member offered up his, which is well loved but in fine condition. It’s now gotten enough use that I think a review is in order. I’ll try to update in a month or two once I’ve reflected more.

Fit & finish: It’s a used, well made knife with a D-shaped ho/blonde horn handle. The spine and choil are slightly rounded, but not totally smooth and polished. Good enough to be comfortable. The knife itself is iron clad B1. No delams or anything negative to note. The handle is quite large (more on that below). There is the tiniest bit of machi gap noticeable in the handle install.

In action: If I was good at waxing poetic, this is where I’d do it. This is my favorite gyuto profile. Subjectively, it just plain works for me. It is born to push cut, has a nice low tip, but isn’t so flat to make a little rocking annoying.

After running it through all manner of produce, it did a good or better job with everything. But, I won’t say it’s perfect. There was some carrot cracking and melon really stuck to the blade face. But cabbage - holy $&@# - I’ve never gotten more thinly shredded cabbage than with this knife.

It has decent distal taper and the tip is thin enough for garlic, cherry tomatoes etc.

The knife arrived fairly sharp and so far I’ve only done a touch up on an aoto. After a minute or two it was easily going through soft tomato skins.

This is a reactive, iron clad knife. Like Mazaki reactive. Hopefully it builds a deep patina soon, because my steady use of 52100 knives has made me a little less diligent on the wipe downs.

Specs: Length - 256mm; Height - 49.5mm; Weight - 198g

Closing thoughts: I’m very glad that I picked up this knife. Every new knife is fun to try, but nothing has felt this natural for me. My mind could change, but this feels like it’s permanent in my drawer unless I get a direct dimensional replacement.

That said, I don’t care for the handle. It’s longer and has a larger circumference than any other knife handle I have (including 270 suji and 240 gyuto). My personal preference is for slightly shorter handles anyway, so this one isn’t really my style. I like the blonde horn a lot though, so I’ll have to think long and hard before replacing the handle.

You don't have to replace it, you can aks someone to make it a tad smaller/shorter. Should be a quick fix.

Thanks for sharing this, seeing old posts referencing miz ks have left me intrigued. Do you know if he still makes this shape?

Just a thought but might consider @Knot Handcrafted. My new suji is right on the cusp of gyutohiki and of similar profile.
 
Not a bad idea. Mizuno has just been on my to try list for a few years. In any case I am trying (ie struggling) to not purchase a new knife for a bit lol

Oh I totally understand the purchasing thing. I mean I certainly wouldn't want you to be tempted by a price that is probably half or less of the Mizuno. I mean you could even tweak it some to your personal likes. But I mean, yeah, we have to be disciplined in our convictions and stuff.




:p
 
Sounds like these are quite a bit different from the regular Masamoto KS? Whether that's better or worse probably depends on the beholder.
Masamoto is mono white #2, this one is iron clad blue #1. Also seems quite a bit chunkier? Probably means it starts tapering later / less than the Masamoto.
Profile looks quite similar enough though.
 
Yes, clad vs. mono is going to give it a little different character.

Not sure about chunkier. Most Masamoto KS specs I see put them right around 180g. With the Mizuno having a pretty chunky handle and both knives being handmade, a +/- 20g difference doesn't seem to be that significant.

FWIW my Masa KS is 163 - and that's with a fairly soaked handle. Though I've also heared there's been quite a bit of variation over the years.
 
cuts significantly better than masa ks and infinitely better edge retention yet feels nearly as good on stones. profile still goes to masa but close enough.
That blue 1 was a revelation. Really hangs onto an edge and a dream to sharpen. I’m actually thinking about getting one of his 210s in blue1 but I like this pointy shape better
 
Took @daddy yo yo ’s suggestion and tidied up the handle a little. Removed ~7mm of length and narrowed the handle a little by eye. Re-sanded to 320, a quick smooth at 600, then buffed the horn up to 3600.

Feels more comfortable, if a little forward balanced. It’s now right at the first kanji.
