The Centofante has a fairly shallow hollow grind. I took mine to a diamond stone and turned it into a flat grind. It's nearly zero ground and the edge was easily damaged. Chipping and rolling. After a few sharpenings it's better.
The geometry was too aggressive. That said, I don't think it's a very high hardness. I would guess upper 50s.
I'm attaching a photo. You can see the edge damage. I didn't want to sharpen it all out. Interestingly, I used the knife after regrinding only one side and it was perfect then. Cut much better while still retaining strength.

There have been a few people here who have tried to zero grind saber grinds with not so great results. Cliff Stamp took a Pacific way down, I'm sure he has a video of it on YouTube. I took a ZDP Delica down to about 10dps with no micro bevel and it wasn't pretty. I sold that knife to a guy I used to work with and he murdered the edge and I even put a healthy not-so-micro micro bevel on it. Then he had it "professionally sharpened" on a grinding wheel...

I'd love to see 15V on a Delica AFI flash batch. I know Sal and BBB were discussing the steel in another thread, along with protocols for ht, and a sample batch Spyderco has to test out. It kinda seems like the perfect match. We're looking for a high performance steel and Spyderco just so happens to be expecting some 15V to arrive soon by the sounds of it. Spyderco doesn't often send U.S. steels to Japan, but an AFI run would make for a good excuse to break that rule. Just once.

Thanx Shawn,

Would you please email your exact tempering method? We're expecting a sample of 15V and we'd like to try to see if we can do that in production.

sal
Yes, I'll send over the latest protocol.

Thanks Sal.

...But in general, I'm all about high performance, Ergos, safety. That's why I've been accused of "deigning in the dark"...

In concept I'm on board 100%, but the task of picking a design, steel, color and bevel that gets 250 AFIs excited enough to purchase is going to give Sal, Eric & Co. nightmares...

I'd vote for the Centofante 3 (or 4) with standard stock thickness, but in FFG, with a "safe" scale color, or an N5 LW that's ground thinner behind the edge, but has the same spine thickness.

Also, in my opinion any super slicy AFI variants (if ever actually produced) should feature high edge stability steels and be heat treated for near maximum hardness... no S30V need apply!

A Nilakka in AEB-L, Blue Super or 52100 would certainly grab my attention.

still more knives than sharpening stones...

I've converted a few saber ground Spydercos to scandi grinds. This one has a microbevel but its been stable as a beater.

I've taken some to the belt sander too although I prefer doing that with other brands that I consider more disposable.
