These knives are designed with a 60 degree angle bend from handle to tip to enhance natural motions from punching to plunging, with the knife being a true extension of the motion. They are designed for off side carry, and have several carry options. The arcs on the ring serve as natural finger/thumb/palm (hypothenar) placement points, and becomes a natural extension of the handle when fully enclosed in the hand in either forward or reverse grips. You also have the option of using the ring in reverse grip (much like a Karambit) but with a straight blade you can still trap and cut with. The recurve blade comes to a hard angle before transitioning to the tip, and this one offers a top edge for a full continuous cut.
These knives have an M.S.R.P. of $350 and available directly from Andrew Bawidamann
