Woof Rory:
Although I can be seen in DLO 1 demonstrating a quick draw with a knock-off of the Emerson Kerambit waved folder, we don't really have any kerambit specific material in our curriculum, though the material for edge out reverse grip slashing is biomechanically relevant.
Concerning our knife curriculum, we have a distinct preference for knowing with whom we work. The material shown in DLO 1 & DLO 2 is counter-knife, and the knife attacks shown are thus commonly used by thugs and untrained people-- in other words, we seek to avoid helping the bad guys develop their game while at the same time helping good people understand what common bad guys attacks are really like.
Does this answer your question?
