Re: hollow grind
can you file a hollow grind with the wicked edge?
You certainly can mate. The hollow grind is the way the blade has been ground, but you will be working only on the very edge. You can put whatever apex on the edge that you like.
I ran into a similar problem with my full convex ground blades…I wanted to put a different edge on instead of a convex edge and I did. No problem. You can do the same with your hollow ground blade. I have a Buck 110 and it is hollow ground…I put my own edge on, no difficulty.
