Has anyone tried drilling, milling or in other ways machine their CS drop forged knife?
I bought one of the boot daggers mostly for the same reason as the OP, because I didn't have any true dagger, because it's 52100 and because of looks and price.

I'm not very likely to ever use it, but that doesn't stop me from thinking about modifying it, it is a bit handle heavy, and while I've found the handle pretty decent, a micarta grip might make it better. So I have considered drilling out the middle part, stripping away the paint from it, and install micarta (or maybe even wood) inlays.
But if the handle is at same hardness as the blade, the drilling/milling part will be awful, and better to just forget about the idea...
