Is it important to avoid the micarta?

Didn't sand properly, took off a lot of material and probably ruined the heat-treat.

I've often wondered what it takes to really ruin the HT of a blade. I dont know much about metallurgy but the general rule of thumb I was taught back in shop class was that when you sharpen a drill bit or chisel, as long as you don't heat it enough to change the color you're good to go, and if you do you cool it and grind until you get past the color.

Bottom line is: you don't know and won't know until you USE IT. Go use it. Really beat on it. That'll show you if the heat treat was compromised.

Busse shouldn't give you a new knife if your wacky brother in law scratched it up. Go use your knife.

You won't ruin the HT of the whole blade if you cool it in between properly, but the thin cross sections at the very end of the edge can lose hardness very fast with dry grinding.

That's my thinking. The knife wasn't broken so there was nothing for Busse to warranty. If it was broken and then the warranty declined because of the sanding, that would be a whole different matter, but taking an ugly knife and making it pretty would be more of a custom shop job with the cost falling on the owner.

......If you cherish a knife, don't loan it out.

Yep. And that rule also applies to anything that you cherish.
