There are more Kydex benders than Leather Masters. I am NOT saying bending Kydex and getting a really nice product is easy, just easier than carving and gluing/sewing leather. Also Kydex usually has a faster turn around time. IF they have the blade you want a knife for, a Kydex sheath can be made a lot faster (at least I think most of the time) than a leather one can. I have both, and believe that there is a place for both types. IF you want to just toss a blade your vehicle and forget about it, or your pack, or whatever, Kydex is probably the best option. It won't draw moisture nor will it rot or dry out like leather will. Also If you are going into a wet environment Kydex will probably be better.
