For a small fix blade tactical type do take a good look at Bob Doziers work. His best belt sheath IME is the same type he makes for most of his small fix blades: a near horizontal with a quick on/ off belt clip. It can be worn strong side abdomen, crossdraw, reverse cavalry (just off one side of the small of back) or slipped into a coat/ jacket pocket. The belt clip acts as a lever for the thumb to push off of as the rest of the hand squeezes the handle and POP, the knife is drawn. For a combination of comfort, compactness, concealability and accessability it is hard to beat.
The pics of this sheath in his current literature (old)and on his web is a bit outdated. The sheaths profile is currently rounded and very minimal in size.
NOTE: Bob was the sheath supplier/ designer of Spydercos first model Moran fix blade.

Oh BTW, his prices start at $35 for a belt sheath while his neck models at about $25.
