Its basically something called a kubotan. You can get it from a self defense store for like... 15 dollars maybe?
But here´s the DIY part, thats nifty cause you probably wont have to buy anything.
Its basically just a marker... probably one thats about 6 inches, kind of like a permanent marker. The one I have felt sturdier than the normal aluminium ones, so i kept this one. You´ll want to use a stick that´s really sturdy.

Thats mine.
Originally, you grab a kubotan so that both ends stick out of your hand, but since this is shorter, and youre probably (like me) not really good at being strong, youll wanna grab it like this.


So you will hit with the marker downwards, like if you were stabbing a table with a knife.

Also, try to put your thumb on the top, so the marker wont slip when you stab with it.
You´ll want to do downwards stabs, towards any bony area of the body (try not to hit the face, or you could kill someone. seriously).
The point of using a sturdy marker is that since it wont cut, it will have a great impact damage, so if you hit a bone, you are most likely to break it.
Good points are:
The sides of your chest, a little below the armpits
The armpits, if youve got good aiming...
The opposite of your elbow, where your arm bends
The shoulders. This is a pretty good spot, cause if you break a bone there, your attacker wont be able to use his arms anymore
The clavicle is great, but that´s a little harder to hit. It´s the bone between your shoulders and your neck.
The middle of the chest, the part where all the bones meet
The bad points are any fleshy parts, like the stomach or some muscles. Although it might hurt in the muscles, its not enough to stop the attacker, so i wouldnt recommend it. In the stomach it really doesnt hurt that much.
I was hoping you guys could put this to good use. Since its just a marker, a cop can stop you on the street, and he wont do anything cause its just a marker. If youre walking home late at night, you can carry it in your hand along the street. If you go into a show, you can take the marker in with you.
I hope you wont use it to go around and getting into fights (i know you wont) but in that special case where youre about to get beaten up or raped, thats a good moment. Also remember to get the sturdiest one you can find, you dont want it to bend and get ********. razz
