The Gryphon M-10 is an outstanding little defensive knife and perfect for JAK's Drawpoint system! In fact, it is the knife featured in his Reverse Grip (Drawpoint) Knife Fighting tape, which IMHO, is the fastest way of responding to a surprise attack. Rob Hummelbaugh (Survival Sheath Systems) makes a great multi-carry sheath that comes with it, and can also be set up in one of his excellent shoulder rigs. While the sheath will adapt nicely to IWB carry, it is not set up for absolute speed and grip acquisition in reverse grip, so I made some up that are similar to the one used in Keating's tape.
