I am certainly not talking about using it as a knife disarm. I have a Sig 938 for that.
Edit: actually it was someone else a few posts up. I've used it with quite a lot of success against people (without knives), the surprise factor seems to work quite well although I can't say I throw it with any kind of power.
You don't have a knife, do you? :-P
No worries. The internet can be weird that way. Of course, you're in one of those civilized countries where people don't typically carry firearms and I'd bet carrying around a cricket bat for self-defense is typically frowned upon.
I've seen the crescent kick taught as a knife disarm, but if I didn't know better I'd say that people picked up that particular bit of silly in the 80s watching terrible martial arts movies. (They are fun to watch, but good god they're awful.)
As I said a few posts earlier, my thought on the best defense against an armed opponent is a good pair of running trainers.
I took a Chen Tai Chi class once in which we were taught a "bunkai" from a form -- stand in low horse stance perpendicular to an attacker (on my right), then turn towards him, strike "the bladder" in a whipping motion with the back/fingers of the left hand, then follow it up fast with a hard right hand hammer fist to the bladder. The theory was that the first strike would cause him to clench the bladder, so that the hammer fist would do some real damage (also, he'd probably wet himself). Aside from the fact that my face and head were completely open the whole time, I wondered if it were not better to just skip the first warmup strike and just use the hammer blow to the groin.
I think there's also some earlier reference in this thread to the idea of using a preliminary first strike to get a tensing reaction, and follow it up with a real shot. Is this a sound strategy? Wouldnt you want to make that first strike count as much as possible?
I thought it was hitting two people for the first 2 years I trained at the Bullshido Shaolin place.
Turns out, having your arm in the back gives you longer range and helps you balance as you punch the guy in front of you.
