Hey guys. I was wondering if anybody knew where to get a new sheath for these knives. I can't find my rivet tool... anyways. The upper most rivet which contributes to the tension on the knife (i have the first run of knives from WAY back) was loose from the get go but having had paracord through it it made not much difference. The other day it fell out completely and i don't trust the knife in the sheath now. Any ideas?
