FOLLOW ON QUESTION: HOW CAN I SOFTEN THEM?

This morning I stopped at our local tractor dealer to get a chainsaw chain sharpened. The guys there knew I made knives and said "Steve we have something for you" and promptly produced these two blades. Even they were not sure what they were but probably some kind of a cutter on a big tool. They thought I could make some kind of a knife from them. They are hardened and they look pretty dangerous just sitting here.

So any ideas on what I can do with them? Serious or humorous?

And because they are so hard, any hints on how to soften them so I can grind and drill would be most welcome.



Thanks!!

If they had a bend I'd say they were flail cutters. As they sit I'm guessing they're tips for a segmented rotary cutter. They might make decent smash/prybars.
 
Perhaps if I leave the serrations as they are (or most of them anyway) profile the leading edge into a ">", put an edge on both sides of the ">" and then somehow add a long straight handle, 4 feet long perhaps, and use it to impale Zombies as they come through the front door of my house.

Sort of a spear.:D:D:D
 
I had a commercial brush/weed cutter that had blades similar to that.It was like a weedeater that had fixed serrated blades instead of string. The blades were reveraible to double the life.

I ran a trail trimmer for Parks Canada that had similar shaped teeth inserts.
 
Would be nice to have an idea of the steel. From the differences in color of the oxide near the teeth , that blade was zone hardened with torch or other methods. My thoughts are that
means the carbon content is not very high. Like 1050 perhaps. Tooth area is hardened for wear resistance while the center of the blade is soft for toughness. Yes you could reharden but it wouldn't be a high performance blade.
 
By no means am I an expert on anything, but I don't think you could be any worse off by annealing like standard high carbon.

Treat it like it's 1080 and see what happens, you will have some scale and decarb to deal with but it will anneal or it won't.

Maybe some people with more knowledge will chime in but those crazy saw teeth are distracting everyone!
 
You could make a little pocket multi-tool out of them. Put a bottle opener on one side, saw tooth, and little pry tool at the front.
 
MBurks, if you do a ' subcritical anneal " you won't have scale or decarb !! 1200F for 2 hours .

Ha! I was trying to think of any drawbacks to just go ahead and try to anneal, that's all I came up with so essentially no drawbacks.

Either it will be soft, or you will be exactly where you are now.
