knives? ohh yeah. im an edge freak. knives, swords, maces (spiked, not edged, but hey) axes. lots of fun.
on throwing knives, you want to get really good, practice with knives not made for throwing. helps you learn proper balancing. when you move to perfectly balanced throwing knives, its easy. when i practice, i move between throwing knives, blowgun, and my springer. get tired of one, move to the next.
the sca fighting, expect to A. spend lots of time on your armor,
B. get LOTS of bruises, and C. see a lot of not really realistic fighting.
