Ah, yes, the DM. That was my first attempt to do a satin finish with my belt grinder. It was not my original intent to change the shape of the blade, but in the process of trying to get a full convex grind from the top on a very thick blade, I removed too much steel from the edge. It cuts very well, though, but it doesn't look like a Dumpster Mutt anymore. I did a much better job on the HRLM.
