Reground, Reprofiled Richmond Ultimatum in M390

Can I get in on the tail end of this passaround please guys?

Hi tk, great work! i have a m390 guyto coming my way, but I doubt the grind will be perfect for my liking. How do you reprofile the grind? Stone or belt?

Landed in TX. Will give it a good workout. Very nice grind. Much improved over the factory grind.

[labor of love]

anybody care to comment on how well it sharpens up? how is the edge retention?

[Miles]

Finally had a chance to take it to the stones. No problems. Sharpened up nicely. Did note some very minor fine microchipping prior to hitting the stones. If it came with the kind of grind it has now, I would be very tempted to buy one.

Will give it a good workout and report back.

I put it through its paces, not surprised by the microchipping. Never sharpened it. Held its edge reasonably well. Tinh put an excellent grind on this knife. Very similar to my Shig. If it weighed a good 70-80 grams more, and was 5-6mm taller, it'd be a great knife IMO. Never handled it without tinh's mods, but it screams crappy ITK ripoff to me(without the mods).

My buddy has one which he referred to as a hatchet. It's pretty accurate.

My Mario Makeover started as an Ultimatum. Night and day before and after. The steel seems pretty good. It sees a lot of use.

I did almost everything on a belt-grinder. I did use a stone periodically to evaluate the grind, keep track of any warping issues, and to get the edge profile smooth.
