IKAZUCHI AS 210mm fron JKI

I told a cook friend to check out these cuz he was looking for a 210mm line blade. He brought it to me to treat the handle & saya. I use Stepan's mix because I used a few of his handles at work & his finish holds up really well. Found it works good with Ho wood. Tung Oil waterproofs & the clear shellac speeds the drying time.







This is the thinnest san mai blade I have seen with a quality AS core. Not that good at taking choil shots don't know how the speck got there not part of the blade. But you can get the general idea this is a thin blade. The handle seems a little small, but it does look good for the 210mm. I figure the 240mm handle may be slightly larger. It is a light knife.

I etched the edge to see the clad pattern. Then sharpened it on 4K gesshin. 3% thinning bevel & 15% final. Stropped on leather.



Started out with vine ripe tomato. Then cut potatoes, carrots, bitter melon, onions, fresh garlic going to make some shrimp curry tonight. This blade cuts very well, little sticking on potato expected for a laser type blade, it glides through different vegetables with ease including carrots.

The saya was not drilled I like pins so drilled it. At 180.00 for the 210mm and 200.00 for the 240mm feel that these are a good value. The grind is thinner than other AS clad knives.

Do this quite a bit for cooks. this is Ho wood not scrubbed after 3 years in the trenches



Couple handles after treatment

Photos not working for me! Thanks for the write up!

Some were working but now all of them are not.

They are loading for me don't know what the problem is.

How is the weight? Is this essentially a laser?

you may have to change the permissions for these pictures on your google album

Yes, I have a 240mm gyuto and it is a laser. Light and very thin all around. Don't have the specific weight at the moment. I added some Tru-Oil to the raw ho wood handle. I also etched mine and it looks quite dramatic at the stainless cladding border. :doublethumbsup:

I saw a side-by-side choil shot with a Ginga and unless my eyes deceived me--which they love to do--it was noticeably thinner than the Ginga...so, yes on the laser....even though it wasn't attached to a shark's forehead.

Any pic's of that etching? Curious to see how it turned out

First three are not but next three are, maybe there is a difference in how they are posted?

It is little thicker at the spine than Ginga, bottom 1/3 of blade is very thin. I put my Gesshin Ginga stainless side by side the Ikazuchi is thinner behind the edge.

Don't know what is going on not a tech dude load pics from google chrome. Insert, paste on thread they load. Both threads I can see all the pictures but no else can??

Still nada for me.

same, can't see a thing

Sorry for the bad iPhone photos, but all I have at the moment.

A little better focus on the thinness. I really need a photography lesson.

Those I see! Wow.

Any chance you could weigh it? (Manufacturer's spec are often off a lot) And give an idea of the balance point?

for what its worth, the weight we list on the site, is an average of a few different blades, which is usually more accurate. Where it gets off is when the next batch they send is different (in the case of kochi, for example, where we have constantly provided feedback in order to improve what we were doing). In this case, the weight will not be changing for a wide variety of reasons.

It is an overall light knife both the handle & blade are light. As mentioned my example was oversize at 216mm it weigh 134g on my scale. The 240mm on Jon's site is 143mm. My Gesshin Ginga 240mm Stainless is 134.2g.

I meant 143g

My 240mm Ikazuchi gyuto is 135 g. In comparison I just weighed my shigefusa 210mm gyuto and it was 172g.

I imagine the ho wood handle helps tilt the balance forward which IMHO helps with momentum chopping. So bottom line, more weight than a laser, but a thin grind that performs well, and good steel and price? So if you don't need a weighty knife for chopping, a pretty fantastic knife at the price?

Its notable taller than the gesshin ginga, which explains the weight and how it is able to be thinner behind the edge.

I'm confused...on the site I see both @ 48mm? :scratchhead:

How tall are the ones you folks are seeing?

i think our ginga measurement is a bit off then, because side-by-side, its pretty clear... i will have someone check that while i am in Japan

Sorry, didn't realize you'd already started your trip. Enjoy your travels!

FWIW - This is from most recent "batch". GG Stainless. (It would convert you Jim)

Not so sure about the stainless part, but looking to add a true laser at some point. Love the new Ikazuchi line but can't quite get past the stainless cladding. Been planning on a mono White 2 from the GG line and so far this is still leading the pack. Don't you have or had a Tadatsuna for comparison?

interesting... i'll have to take a look when i get back. In the meantime, i have someone re-measuring stuff at the store.
