Hey Bud, don't have any links, but do a search on James Keating, and his "Riddle of Steel". Trite and to the point... take a paper clip, make it like a fish hook, tie a THREAD to it ,then hang it from ceiling etc. Take notebook or thinner paper hook it to the paper and "Fight It". start with fast cuts on the corners. It'll (paper) move around a bit depending on currents. you can stab as well. Object is to not 'tear' the paper done. Speed. DO NOT HAVE ANYONE around. Use a lanyard of sorts. You can do the same with a ping pong ball. Although you are not really trying to cut or piece it. Works wonders on hand/eye co-ord. I primarily use the later for finger jabs. hang it were you encounter it at least 1000 times a day.....
