Incredible!!! I will certainly keep you in mind for when i have got some extra cash on hand!
Any chance you could fit one with some ironwood and brass Corbys?

Sorry, do not use wood and glue anymore.
To much problems even when wood is stabilised.

Micarta and G10:
1. does not change dimensions
2. does not affraid of water, acids, oils and so on..
3. screws allow to put changes into the knife once made quite easily

1 + 2 + 3 = more useful and non problematic tool which I make.

How rust resistant is O2 compared to your M390 steel? I live in a wet humid environment (Louisiana) and I usually won't get anything but Stainless. Thanks AD.

NONE

O2 has about 0.4% of Cr (just enough to be harden in oil) and M390 20%

You need about 12-14% of Cr inside (dissolved chromium) to call steel STAINLESS.

You must look for M390 or Elmax knives to have "nonmaitenance knife"
