I just got a Bulgarian AK74 bayonet (one of the modern ones), heck of a good knife for $28.95 from Gunaccessories.com.  My question is how do you go about sharpening this bayonet ?  I know how to sharpen knives, just never had one with an offset edge before and I don't want to wreck it.  Not sure if this belongs here or the blade forum, mods, please move if you feel the need to do so.
