edged weapons are hard, edged and rounded are harder! i was once attacked by 2 guys, no weapon showing, we got in a fight, still no weapon vissible, an all of a sudden - WHAM - there was an ice pick flying at my chest, MA taught me the best thing to do was move, i didnt do it fast enough so now i have a perfectley round scar 11inches from my heart i defended quick enough to stop almost all serious damage from occuring although i still find it hard to breath in cold climates
