I bought this knive (possibly the only left handed on the market) from Master Bram Frank. This knife has so many possibilities that even after instructions from Bram, I keep on finding new movements and actions that are possible with this knife. It has many areas in the knife to be used for defense even before you open it. Some of this areas are for pressure points, strikes, pinching, even to help you do joint manipulations and of course a very nicely sharp blade. Has anybody else has any expirience with this knife?
