Man, hard to say who.

Kydex--David Brown, Steel Nut from BF, and Mashed Cat is who I have. I say go with DB since he is a member here.

Leather--Rainwalker, Savage, Holloman, and Chuddy Bear. RW and Savage are both members here and I like them both. RW can do magic as you saw with my MPLE sheath.

Nylon--SY for a DF and a Spec-Ops. Neither of these offer anything for the blade you have.

Make it a good one since it is going on a psecial good looking knife!
