Hi all! I have been debating modding a green river 4.5in belt knife for a while, but need to ask a two questions first. First off, does anyone know the rockwell hardness of these things? Somewhere in the mid to low 50's? Secondly, will a dremel, hacksaw, set of bastard files, and sandpaper be enough to modify this knife into a kephart pattern? I know that they sell a knife already in that general spearpoint pattern, but I don't care for the five inch blade and the weird serration like grooves on the back of the blade. Any help will be greatly appreciated!
