I never even had anything close to a "real" throwing knife when I was learning to throw. I was a teenage kid, and I used butcher knives, steak knives, screwdrivers, butter knives I put on the grinder, pocket knives, hollow-handled 1980's cheapo survival knives, anything and everything. Needless to say, I broke a lot of crap knives in the learning process, but I also found out that a decent full tang chef's knife, wooden handled with an 8" blade is a pretty reliable thrower. I'm fairly confident that as long as I was within 20 feet, and had enough knives, I'd be a pretty scary opponent, especially if I practiced my rusty-ness away. I had a 90, 95% "stick rate", as long as I was within that 20 feet and could half spin the throw. Exponentially less with increased distance, but still a pretty sure thing up to about 30 feet, and which point I'd say any opponent would probably be ok. the trick for me would be to wait until the distance was at that sweet spot. I also agree with the guy here who said it was hard to miss a man sized target at his chosen distance, same for me. I scarred the heck out of a huge old tree - (yeah, I know, now)-I used as a target regularly, at exactly "chest to head high", and if I got a throw "in the groin" that was always good for a chuckle. I practiced underhand, overhand, side-whipped, moving, walking, backing up, two hands at once, quick repetition of about 5 knives (nothing like thud-thud-thud-thud-thud for showing off) with varied success but I could always count on the plain old overhead half spin, held by the blade.
