Aichi ZA-18

Is this steel any better in performance than VG-10 or N690? It looks to have a little more this and that, but very similar to both.

Do any of you know anything about this Japanese steel?

The higher chromium will make the carbides more clumpy. Not ideal. Which is why I'd prefer the VG10 and 19c27 over the N690 / ZA-18.

ZA-18 doesn't seem to be very available to play with, no desire either. Nothing significant, n690 analog.

Wasn't that the one that was supposed to be an upgrade to VG-10?

I don't think I've ever actually seen a knife made from it.

Additional Chromium in N690/ZA-18 is not ideal. It's a balance between Carbon and Chromium volumes for the more desirable smaller carbides for Edge Stability

I ran across this steel and had never heard of it. I guess it does not offer anything new.

Doc, I’ve had the steel in a petty knife from Kanetsugu’s Pro J series. It’s a nice stainless kitchen knife steel, but I really couldn’t say I would have noticed a difference if I had been told it was VG10.

I ended up selling the knife to an acquiantance who was going back into chef work, when I consolidated my kitchen knife accumulation. He likes the steel better than the German 1.4110 type knives he was used to, but that’s not really surprising.

It’s just another steelmaker’s take on a very popular Japanese proprietary grade.
