Slight correction. 100% bainite is possible up to .118 sheets. Were those pics taken at the edge? Are you trying for the same microstructure all the way from spine to edge, or do you want a soft back? Have you tried quenching in molten metals? It kinda defeats your goal of only having your salt pots and getting rid of the oil, but it may avoid the pearlite. The trick is finding a metal that melts at the proper temperature. Tin is the lowest I've found and its still 450 F. I'm with you on fillet knives. I'm trying to make some small utility knives, 3" blades, 5/8" wide. The last knife I made was 1/8" when I started grinding, but ended up w/ a full flat on 1" wide stock and the spine dropped to 3/32" by the time I fixed some grinding errors. It cut so well, I figured I'd use that thickness to start with.

Kevin,I read all of you and mete's posts with great full appreciation.Keep them coming.
One problem with Me2's post is the finished product he is trying to create.He wants to do a very controlled set of heat treating steps with ,"WHATEVER FILES ARE MADE OF".You need all parameters to do what he wants.Mystery steel,and used files would best be quenched in 135 degree oil. Would you want your brain surgeon to operate with ,"Some Kind of Scalpel." I would recommend using a steel with analysis specs from a good supplier if I was to do Marquenching (Which I feel is of little advantage to knife makers,and would be of no advantage in this case).
Me2,the ironwood used in decking is not Desert Ironwood.It is a good hardwood,but isn't particularly beautiful.It is usually ipe.Occasionally it is some species of hornbeam like carpinus caroliniana,sometimes the Australian ironwood.Desert Ironwood is olneya tesota, and is a completely different animal (or plant).
