Was in a remote mountainous region in Asia, and had a run-in with some of the locals at a bar (my colleague's fault unfortunately - he objected to the way one of them spoke to a woman and decided to get involved, fists-first. Whichever way you spin it, we definitely weren't the good guys in this situation). Things escalated rapidly, and one of them tried to draw a weapon - which made perfect sense really, since i was twice the size of the locals and was having no problems making short work of them. He fumbled the draw, i didn't fumble mine, and having a nasty looking claw-shaped blade against his neck suddenly made him think a lot more clearly when i suggested we all part company in different directions. I learned two things from this:- 1. Forget nifty entry techniques and finishes: If you're slow on the draw, you won't be in a position to use them. 2. Taking a dump and an Immodium before going out was a really good idea.
Wow, I just learned kerambit techniques using the feet! Yup, you read that right, the kerambit is on the foot!
If you are wondering why, it's for that extra appendage that cuts. Most wouldn't think their enemies feet can cut, just like I didn't. Wow, surprising techniques...
Although using the kerambit using the feet can be nice, I would consider them fancy but unusable techniques, unless you live in an environment where you walk barefoot all day. I did see an indian style that had knives integrated in the shoes....that might come in handy
My exposure to this weapon is rather limited. I have a few just gathering dust in my weapon bag. I still cannot get comfortable wielding them as much as I do with conventional knives.
