all amazing advice, but on the keys between your fingers one,
donāt put your keys between each finger:
if you hit someone with them, it will bend back and hurt your knuckles
you need to be facing an attacker in order to hit them, so if someone attacks you from behind you wonāt have the upper hand
it isnāt sturdy, so if you punch someone, it will move (it will hurt, but itās not ideal)
instead, hold your longest key in your fist like this (itās just a quick sketch, hope it gets the point across) (sorry if i described it badly, can anyone else describe it better for the blind peeps?)
itās sturdier, meaning it will do more damage, and wonāt bend back, hurting you
and you can hit an attacker from any direction, even if they come from behind
