I don't kid you when I say they are sharp. I cut one of my muscles straight through (please don't ask just clumsy), even the doctor was impressed, needless to say my father was not.
I still got all of my equipment since my martial arts days left but I don't practice anymore. When I broke my ribs for the third time I realized that I was getting to old, still love the sport though.
Nice to see that others have similar background and still manage to do some training.
