Mac: I'm not sure if Krav disciplines vary from group to group, but we had two instructors. The first was a world-renown Karate (i believe, may have been Kung-Fu) master that gave up a lifetime of work in the discipline when he realized that it didn't actually prepare students for real fights. He took up Krav Maga shortly after. Our other instructor, an awesome guy (250 pounds, very little body fat), was a SWAT team leader. It was the latter individual that I was quoting. The 'dojo' Sharp and I used to attend (school and soccer season stopped my attendance, sadly) also taught a lot of people basic survival fighting.
Ahh those two... <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
Cloak, M was a fifth dan in Jujitsu and L, shortly after we were there, became SWAT Commander.
Two very cool guys and great instructors.
L was hilarious. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
I'm sad that they moved so far away and got a really nice big place to practice at. Showers, weightroom, etc, etc. Full gym basically.
Anyways back to the topic of self-d.
I've usually looked at a knife as a tool and still do. Our primitive ancestors rarely, if ever used the knife as a weapon. Many indigenous people all over the world use the knife as a tool rather than weapon. They have blow guns, bows, traps, swords, etc, that work far better as weapons. The knife has been for the longest time a tool.
While it is easily concealable weapon, one must remember that in times of emergency one will forget all that they are carrying and only remember the importance of their own will.
If that makes any sense, I'm trying to say that if anyone of us do get in a sticky situation, we will most likely forget that our knife is IWB, and immediately use whatever is in range that we can see as a means of defense. Which would be our own body and mind.
Unless we're highly trained individuals in knife fighting who have the muscle memory down so that when SD is necessary, the first thing stance that we get into we would have a knife in one hand.
I admit that sometimes when I'm walking in downtown I do get paranoid and just think "Spyderco in right pocket will come out if some one tries to jump me..."
