i dont like how DM's fit in the spec-ops.i dont think the blade is wide enough imo.it will work but for me i dont think it works well.

something as small as a DM i put in kydex.i think thise spec-ops are by far the best nylon sheaths around but are better for larger knives like an rd-6,rd-7,YH,YG,S6 and stuff like that.

just thinking out loud.
