Until further notice, all Emerson knives will be sold directly through Emerson. We apologize for any inconvenience. The announcement of an Emerson knife with a flipper and ball-bearing pivot has created a frenzy of excitement. The Rangemaster Sheepdog project was prompted by Lt. Colonel David Grossman, a former Airborne Ranger and West Point Instructor. He is well known in the military and tactical world and the founder/owner of Sheepdog Knife and Gun. The Rangemaster Sheepdog knife has a familiar, time-tested build with titanium liner lock, G-10 scales and a 154-CM stainless steel blade that still comes with the standard thumb disc and Emerson's patented Wave Opening feature. This model has a Spear Point style blade with a black finish and partially serrated edge.
