Would anyone have any information on how to make a gut hook on a folding knife? I have an old fairly cheap single blade folding knife and would like a gut hook on it. I'm not real sure how to go about it. Would ginding the rough out draw out the blade temper? I have a round ceramic sharpening rod for the final edge. The purpose of this gut hook is for small 'tree rats' as it would be easier for me to carry a folding knife instead of a larger fixed blade. The blade length of the proposed gut hook blade is about 2 1/2". Any help would be appreciated.
