The Karambit is mine and several other instructors personal carry of choice. We all have the Emerson because of the wave feature and ease of deploy. I teach it to fellow instructors as part of my knife material but its not “official” KM material.
With the Karambit you really need to get comfortable with the deploy being 2nd nature from there just think block and instead of punch its deploy/strike same target area as the punch would have been.
Theres other stuff but you get the jist of it. Your welcome to pm me if you have any specific technique questions.
I believe that self-defense is a moral imperative, and that illegitimate force and illegal violence must be met with righteous indignation and superior violence.
But hey, thats just me.
