I spent years working with knives, you need friends that will practice with you, the kind of thing that a lot of physical 20 year olds do constantly, fight, fight, fight.
If your friends during your 20s and early 30s are not the type who love to fight and wrestle and play rough constantly, then you probably need to join a class or something.
Well, sadly, my 20s and even my 30s are far behind me now. I suppose I’ll just make good use of my concealed-carry permit.
