The zytel isn't great, but it's functional and reasonably compact. The A1 really needs an aftermarket sheath... The knife is a relative bargain even at full price when you think about the company it keeps in terms of performance, so spreading out a little more for an aftermarket sheath isn't so bad, I guess. People are right with regards to the F1 and S1 though- the leather sheath is definitely the way to go with either of those.
