Won’t hurt to try. You could always just grind it without annealing and re-hardening. Just make sure that you don’t let it get hot enough to turn blue while you grind it. Just keep a cup of water next to the grinder and dip it before it gets too hot.

If you want to go the route of annealing, shaping, hardening and tempering, you might want to look up spark testing to see how much carbon is in the steel. This may give you a better idea how well you will be able to re-harden it afterwards. You probably want a steel that at list .50 % carbon. BTW, you will also want to temper the steel after you harden it so it is not too brittle. This means that you may want to remove it from the old handle because you have to put it in a toaster oven, for example, and most handles won’t take that kind of treatment.

I’ll have to look into this spark testing.

Maybe buy a cheap 1/4” chisel and grind it down?

What about an 1/8” drill bit? Grind the non fluted end and sick it into a handle.

The problem with converting a 1/4” chisel is the blades are not long but I might not have a choice.
The 1/8” drill bit option may work. I have a few that are approximately 8” long. Now why didn’the I think of that.
Thanks for your input.

Mike, I found your video last night while searching the tube. Great video! I like the way you made your point without loud unnecessary music in the background. Also found a few that some made from old files. I’m thinking I can get a nice Mortise Chisel from one of my old Harbor Freight files since they’re not any good for anything else. Thanks again for replying.

Try using concrete nails available at Lowes and Home Depot. These are hardened and have a broad flat head like hand cut nails that would make into a nice small chisel. Add a handle and you should be ready to go. And a box of them is CHEAP!

Old files work great. I inherited about 20 pounds of old chisels from my grandfather about 40 years ago. Been moving them all around the country all that time until about 2 years ago. That’s when I went on a “make your own tools” kick. I’ve made a set of chisels (1/8 – 1”), a plane, a bird cage awl, and a turning scraper out of old files.

It takes some time to get them into the proper shapes without bluing the steel. Lots of dipping in the bucket of water. A worn 180 grit belt on the belt sander seemed to work best to get rid of the file teeth. Lots of dipping in the bucket of water.
I still have 20 or so triangle files in the pile. Perhaps I’ll just pass them along to my son.

I used an old small flat file, annealed it to shape then retempered.

Would have never even though of concrete nails. I’ll have to remember that one for small things. Seems like the old file thing is the best for me since i’m looking to make it as long as possible, kinda like a Mortise chisel. Again, thanks for everyone’s replys
