I bought this knife 2 years ago. It takes and holds a reasonable edge. I carry it in the knife pocket that's on the outside of my 5.11 boots. I poked 2 small holes in the bottom of the knife pocket. I put a boot lace through the bottom holes on the kydex sheath and then ran the lace through the two holes in the pocket from the inside. I then put the sheath in the pocket and was able to tie the sheath into the pocket. I then tied and super glued a knot and cut off the excess lace. This has never come loose and the sheath is very secure.
