Anyone have any experience with this????
Calls for a rockwell of 63-65 Rc. Should be able cut nails with that.
I guess the addition of tungsten makes it pretty tough.
I think it was developed as high speed steel to be used on tooling such as wood working planer blades, etc.

I have whittled down a machine wrecked blade out of M2 at 63 Rc into something usable.
WOW does it take and hold an edge.

So, I am thinking of making a couple knives out of the CPM Rex M4. It is kinda pricey but.......

Not sure what pattern(s) or how many. Maybe a big camp and a couple of regular size drop point hunters.
Steel available is 3/32" and 1/4" mill finish.

Anyone have any experience of thoughts??? I would welcome the input.
Thanks
Tim
