Militech-1 might solve your lubrication problem needs. It is not a lubricant, but it reduces surface friction between metal surfaces. Unoffically, Infantrymen love it for their guns as an alternative to no lubrication at all on rifles as it does not attract dust in the desert.

I dont know a darn thing about this subject, (wannabee engineer) so here is a diferent perspective: Isnt this sort of thing handled perfectly by a flywheel? I know that is rather old school, but If I understand the problem properly, it would have the effect of damping the system through brute...

I think you should get a second die. If it were so easy to decontaminate tooling, there would not be so many procedures and reqirements for prevention of conaminating stainless.

Highly reactive metals are often kept imersed to prevent oxidation. Wax sometimes is used for long term cutlery storage. However, the wax would prevent the blade from slipping smoothly across the skin unless removed first. Eureka! How about food grade light mineral Oil. It is usually labled as...

What if you stored the blades in Everclear, AKA maximum proof grain alchohol?

Flounder, You were getting carbide separation. This method is used in some knife blades. The carbide separation along with the dendritic structure makes for a "toothy" edge when sharpened. I did search, and came up with the same awnser you did: anneal first...

420 stainless perhaps?

Take a look at Crucible's Crucible Particle Metalurgy steels. Very high wear resistance in a stainless steel. CPM90V CPM60V and CPM30V http://www.crucibleservice.com/datash.cfm Also Have you looked at the various conventional stainless Cutlery Steels? Most of these are based on 440C with higher...
