CPM-D2 RC Hardness

[tasdevil]

I'm going to send a survival knife for heat treatment. What is the ideal hardness for such application

If your going to be chopping and batoning I would go around 58rc I just had a failure on a chopper I made that was around 59-60 but i think it was because I hollow ground it way to thin.

For a field/survival knife RC 58 should work fine, A little easier to sharpen in the field and less likely to chip.

I have used CPM-D2 for culinary knives and I had those taken to 60-61 RC by Paul Bos. These of course are not going to chop through logs or be batoned.

Not to intrude, but I'm curious, do you find that your d2 stains at all in that app?

I have a nice d2 bird & trout-ish knife that I'd like a patina on.

Also, watch the edge geometry. If you're going to be abusing the knife, make sure: 1. it's either flat or convex ground, 2. the edge is a bit thicker than normal and 3. convex sharpen it.
