Some time back I drilled two holes up through the handle top, 180 apart, up through the pommel steel of my Camillus USMC. I did a paracord wrap of the handle from the bottom and brought the pigtails of each end of the 550 cord up through the handle and ran them through a bead to form a slip lanyard for the wrist or thumb. This difference, lanyard exiting through the top of the handle vs.lanyard through a hole down IN the handle, made an amazing difference in handling and leverage when using the knife.
It hangs better and more safely from the wrist while taking a break in chores. Also the leverage it adds for chopping, being able to come all the way back on the handle but still be secure in the lanyard, turns the USMC into a solid chopper and bushwhacker.
