Awesome. I love the wave, and the wide eyed stares it gets me from gun people who have never seen one deployed. Completely changes your assessment of the 21' rule, and brings to light that there is more than one way to fight, especially up close. I have a bunch of Emersons but I'll have to give these a go to see how they hold up.
My combat karambit may be the most versatile fighting knife I have. Its design lends itself really well to techniques that are based on and very similar to open handed fighting.
Imagine doing a forearm block against a stick swing and then wrapping your arm around the weapon and the opponents arm, pulling away,disarming them. Now imagine holding a karambit weak handed, that is finger through the hole and blade down and away from the body, and doing this same motion. Yeah. You'll disarm your opponent. That is, you'll surgically remove your attacker's arm.
If you carry you should absolutely add one of these to your EDC. Probably a good idea to get a trainer too. Also, use a crappy pair of pants to practice with. If you practice with your nice pants you'll wear holes right where the pocket clip grabs. Try to get a smooth, quiet draw that ends with the tip pointing away from you, but hand close to the body, and try and have your grip cemented by the time you get to this ready position. Takes a lot of practice, hopefully with a trainer so you don't lose a toe.
