what about this knife as far as having to stab something goes? this benchmade is about a tough a knife as you are going to find... i think it is shaped well too... and believe me, 2 inches inside you with a blade is PLENTY enough to cause EXTREME PAIN and death..

as far as i can tell that knife has a drop point on the front end which is on the wrong side of the blade for stabbing..... so when u stab some one with a knife like that the blade would tend to stab in a downward direction because the back side of the blade wont cut so the knife moves in the direction wit the least resistance. sooo im not to shure bout that as a stabbing weapon cuz it doesnt look like itll go in and out effectively usually id have a spearhead blade for stabbing alot like the Ti-lite mention earlier would be good and as far as knives go for stabbing id say the longer the better 2inch might cause crazy pain but 4 inches will 2x it :wink:
