Re: Atemi and Aikido
Generally, your wrist should be strong from doing aikido. You should not have to hit the vital points repeatedly. If you do, you're in a boxing match. Conditioning the hands and knuckles repeatedly requires the willingness to pay a price: loss of some function or permanent soft tissue/joint damage. I used to do the makawari board years ago in tae kwon do and still have coarse skin over those knuckles.
