I noticed some negativity regarding the M9 bayonet. Okay, it was and is primarily a bayonet, however, with proper sharpening and some modifications, I think it can be "tickled" into more utility. For example, by disassembling the bayonet, you can add a bicycle handlebar grip to the shank and the knife characteristics are improved. I went to a medium-sized bicycle shop and purchased an Oury grip pair, for $9.99. Look on the net for Oury Mountain Grips (Black) HT6300 / BKMT. You need to carefully punch thru the end of the grip so you have a thru hole (the original grip has a blind hole). I felt cutting off the plugged end shortened the grip unnecessarily. I wanted all the length I could salvage. I used a fresh razor knife but using a short piece of 1/2 inch water pipe and chamfering the INSIDE edge, results in a I.D. beveled one-time punch that leaves a clean hole thru the grip. A good chunk of hardwood can be used to punch thru to. It took some filing to make the bevel or chamfer unless you have a lathe and can really dress up a super punch. We all know patience is a virtue, right ? Here comes the hard part or at least it was for me. To assure the grip doesn't slide around during use, I chose not to lubricate the grip or the bayonet hand piece before I sleeved on the grip. A marine told me he used hairspray to lube the handle. Once you do that, it is difficult to recover if it doesn't work. Besides, I need occasional reminders that my thickheadedness is working as designed. While watching a horror movie, I massaged the grip onto the plastic bayonet handle from the FORWARD end of the handle to the aft end, and I put the "non-punched" end on first so the ridge on the end of the grip ends up on the rear of the handle. This is your call of course. It took me about an hour of vigorous massage to get the grip all the way on. My reasoning was, the butt of the handle is the largest end and I wanted the ridge ring to cushion my hand when thrusting the knife. This is the reverse of the grip as it was intended on a mountain bike handle bar. From my knothole the grip is good and "grippy" , cheap and gives you better torque on the blade. Looks cool too. Bye the way, I did not sharpen the forward 2 inches of the blade much. Remember, that part is the wire cutter (when used with the sheath).
