The largo knife drill is the basic way to teach the concept of Taking The Fang - in the unarmed phase this is the first part of RAT, Entry, with a limb destuction
With sanshin and Kihon Happo we also use a limb destruction - the concept of Ken Kudaki
against a kick it is called Keri Kudaki
as well as intercepting with a kick, as we did in the Kempo lance, we can intercept with a punch, or any face strike, palm, shako or fingers, in RAT Entry phase
we can also wear the boxing glove when hitting with the stick to practice defang
in Kendo this strike is called Kote, which of course means wrist
