the $24.95 sheath WAS sold for the Regulator, but it fits all 7-7.5" blades fine. It fits a 7-11 and a Chopweiler just fine--I have one of each resting in there <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />
There is also a sheath for 6" blades and one for 10". The 7" is my fav, since the retention straps have snaps AND velcro rather than just velcro.
