As an "edge retentionist" I think Game Warden only benefit from more edge resistance being small knife. I have to admit I used one as a chisel once, so toughness is also may be needed for all around knife, but I think to me will be best solution to have INFI Game Warden and Lauri PT GameWarden as well. Or may be Jerry talk to Juha Perttula, doctor in technology at Tampere University in Finland to learn how to do Progressive tempering for INFI so we may have INFI PT Game Warden?
I do not think some experimental runs with different steels will damage Busse business in any way.
last comment first - it's not that it would lower their sales, it's that more knives would come back broken resulting in busse having to do more warrantee work. jerry has said previous (and pretty consistently month by month) that they are
slammed with work.
any steel that can be readily broken by hand
should not be used in a busse knife. It would be a detriment to the companies work flow, and it would go completely against the primary goal of the company, which is to make
hard use knives.
now for the first comment about jerry talking to other people about how to heat treat his own steel... that raised the hair on the back of my neck, even though I know that it shouldn't. peer discussion is informative and useful.
jerry has stated that infi does not respond well to differential tempering or hardening because heat transfers through the matrix to easily. Infi retains toughness and chip resistence at 60rc - if chip resistence is lost, then the heat treating process
should not be used by busse combat.
jerry's direct statement regarding differential tempering/hardening:

the only benefit of differentially tempering infi would be to maintain an spine rc of 58-60rc, while making the edge 62rc+. if infi loses its malleability at higher hardnesses, then it goes against busses primary goal.
on a theoretical level, and out of curiosity, I'd love to know what infi is like at 63-65rc. I'd love to know what kind of edge retention it displays. but I have no desire whatsoever for any knife to actually be produced like that from busse unless it can stand up to their warrantee.
