INFI is one of the nicest steels to polish and sharpen for sure.

I think I actually have the knife you asked for.
The old SH-E is exactly what you described. It is an 8 inch long blade that is not as wide as the ASH. It is not quite as thin as a skinny but the full flat grind version I have is not bad at all. It even has a convex edge although only on one side. The other side is totally flat for an asymmetrical grind.

Might as well post a pretty one.

Here is a nice new Bushcrafter that would also be a good choice. It will also be O1.

I got bit by the spyderco bug (well spider actually)bad recently.

I am having a heck of a time with my own question. Right now I would say my Caly3 and my Rosarms bayonet. Roo mentioned it looks like the Ames Rifleman knife and I thought that was brilliant. I had this feeling like it reminded me of something and he nailed it with the riflemans knife.
