Say that to a Chav Drug addict who just stabbed you to death with a £20 knife, or left you permenetly injured. The sewing machine is quite a thing.It's a linage thing.
Basically without the correct pedigree you are not skilled in weapons.
I don't get it either to be honest.
weapons training is handled differently over different schools and arts, and i don't much expect there is one right and a bunch of wrong ways. My feeling is that movement training is movement training, moving with a weapon is not so different where the principles of movement themselves are concerned, but a weapon changes some things. bad habits you might not notice in empty handed training may come to light when you wield a staff or sword, and in this way weapons training can inform your overall movement practice. likewise, refining your empty handed technique(especially footwork) will improve your ability to handle and learn new weapons.And would you recommend training in one weapon at a time or in more and how many?
