Yes, most of the ones shown were from the knife companies. I keep the Chopweiler in a Spec Ops. I do have quite a few kydex sheaths. I have one for one of my Sarsquatches, but the Busse sheath from SYKCO fits it too. I have some nice leather ones, too, and more on the way. I'd really like to get one like Andy's for my Ratweiler. The cordura sheaths are really quite useful, though. Most have handy accessory pouches and they carry easily.
