I am deploying soon, and I wanted a new sheath for my old Buckmaster knife. (The one it came with is like the plastic bayonet sheath.) I wanted one that is MOLLE compatible, and this one is. It fits tight and snug, the blade is .25 in wide and 7.5 in long, and it snugs into the plastic insert no problem. The snap fastener is adjustable and snug. The pocket is a bit large, I put an old folding knife and a sharpener in it. The cord it came with is not actually paracord, but you can easily switch it out if you must. For a Kabar or M-9 bayonet style knife, this will work great.
Short Combat Master Sheath
I use the short Combat Master Sheath to hold a short Ka-bar Tanto knife and my Gerber Multi-tool. The sheath is well constructed and very functional. I will probably move the multi-tool because it is too difficult to get it out of the pocket. The pocket is actually intended for a sharpening stone which is what I'll put in there.
I don't use the leg cord but I like having the 550 cord available.
