I also had an experience like that in the Philippines. Three of them stopped me and when the one on the drivers side got close I pulled out a cheap butterfly knife and did the flip thing. Well he kinda jumped back and the guy in the front came around allowing me to drive speedily off. Oh and I was actually in one once, stupid drunk Ferner (him not me). Got my finger cut, I got his hand or arm and he decided it was enough. Both situations scared the crap outta me. I never want to have to use a knife again. Like Ray, I much prefer well in my case 25 yards or further. The A10 flies so slow it couldn't make it to me in time.
