a really simple technique can be better than knuckle duster
PS. it is my first instructable so... STICK IT TO ME GOOD!!!!!!!!!
Step 1: What You Need.
1 human fist (preferably your own)
Step 2: Doing It
place 1 coin on your palm below index and middle finger
place other coins through the spaces between middle and index, middle and one
next to pinky.
Any damage you do with this is in no way linked to me and i only suggested the possibilty.
I have seen this done and a coin get lodged in someones face. BE CAREFUL.
"coughs only hit in stomach back and maybe chest.
Do not attempt while drunk
