here though id post this for you entertainment.

Kydex fst is kydex, but with the bonus that it is antibacterial. this is pretty neat for sheaths seems like a perfect application.
you can clean a knife prety easily, but a permanently clean (sort of clean at least) sheath would be amazing!
cutting food, and potentially yourself in the field would be safer
problem is you cant get a hold of any at least not very easily or cheaply
