I have compared the Montecs, the Snuffers and the HellRazors side by side. The Hellrazors are the sharpest out of the package, followed by the Montecs and then the Snuffers.I cannot, for the life of me, find out exactly what the Montecs are made of. I believe that the snuffers are acctually the hardest. I don't think the hellrazors are that hard either. I have taken 14 deer and 6 hogs with Montecs..and I am still on the same original 6....they resharpen fairly easily, but they have a fairly low amount of carbon in them from what I can tell.Still not a cake walk...Iprobably ought to have bought that G5 Diamond stone.
