T-15 tool steel in use?

I would pick a steel like 10V instead. Its much more well known and has exceptional properties. I honestly can't imagine any cutting task someone could do that would require more wear resistance than 10V. If you need more edge retention than that you're probably using the wrong tool.

10V is as tough as D2 and cuts like a hacksaw. It's a really exceptional steel that has great qualities for a knife blade. Another steel to consider is K390. It has similar edge retention to 10V but is tougher. I've ground one small blade out of it but haven't Heat treated it.

Big Chris is a maker here on the forums who works with 10V and will make just about any design you can dream up.

Agreed, don't know why you would want to use T15 when 10V is just plain better. I made a big knife out of 10V and its insane, havent touched it on a sharpener since i initially sharpened it. It hasnt worn at all in several months as far as i can tell.
