I'm wondering what kinds of steel is used in these? The piece I have is around 12in wide and just under 3/32 thick. Thanks,
 
Search for Misery Whip on the Internet. Alan Davis one of our knife makers used these old saw blades for some of his knives.

I'm not sure what a "saw mill" bandsaw is. I know I've tried making knives out of regular industrial band saw blades and I found out they were zone hardened. Only the teeth were very hard. They made better knives than mild steel but a file would bite into them.
 
Relevant to this, there's a guy out there who makes fixed blade knives from new DeWalt "Search and Rescue" reciprocal saw blades. Very tough stuff---made to saw through concrete, conduit, cables, buildings, trains, etc. I think his main biz is forging survival spear heads and things like that.

He makes the edge extremely sharp but the knife is pretty basic in three different grades: Plain, with the yellow and black paint and "Dewalt" logo still on them; grade 1, with all paint stripped to bare metal and blued; and grade 2, paint stripped, coated blade with a wingwalker sand textured handle dip. As I recall all have the new saw teeth remaining along what forms the spine.

Very novel and seem like they'd be pretty cool. If I can find my bookmark for the guy in the next few days I'll come back and post it. I've wanted to get one for a couple years now but haven't. You might be able to find him w/ a Google search..... really worth at least checking out.
 
This is a guess based on fuzzy secondhand memory but I think they're 15n20 for the most part. Don't quote me on that though.:D
 
There is a lot of scrap steel available that is suitable for knives, I'm guessing mostly it is below 1095. I've read about people forging knives from lots of different things. We worry about our knives breaking, chipping, dulling, etc., but look at the tools in your garage that you beat the crap out of and they still work just fine. I've got screwdrivers, pry bars, wood chisels that I have hammered on mercilessly and they just dull a little bit, never break. A band saw blade might be similar steel but I've seen thin saw blades of that type break enough to think that they might be heat treated to a higher level than a screwdriver is.

I've watched those "how it's made" shows and sometimes they show saw blades being made. They heat treat the teeth with induction heating that heat treats a single blade pretty quickly. I don't know if their goal is to not heat treat the rest of the blade or if their efficient manufacturing process just works out that way. If you are making a knife from a saw blade you would have to count on doing a new heat treat on it.
 
I appreciate all the help guys. My reason for the question is I'm wanting to know how to heat treat it. I made a test blade and it has held up really well. I just want to see if I can get the heat treat better and tempering also. Thanks again.
 
Someone on the forum once had European bandsaw blades for sawmills . These are about 12 " wide and a loop about 20 ' long with teeth on both sides.They cut then on both forward and back strokes of the carriage. They were 15N20 !!
