What are folks opinions specific to the SPEAR hand techniques? There are some (?) who train and trained zealously at them. There are others who maintain the stupid myths (to get through samurai bamboo armor) and yet there are lots of youtube demos, etc.. showing folks who can drive their thick stubby fingers through things quite compellingly.

What's your take... "spear hand conditioning" to rip meat off bones? Spear hand techniques one part of the larger toolbox... ? If you have them in what manner do YOU utilize the spearhand and who do you think they are best used IYo, IYE????
