You could hammer a nail into a wall or something but why not hammer a nail and turn it into a tiny sword? That's right. It's a completely silly exercise that could also be a half-commentary on creating useless objects but it also looks like a lot of fun to actually do too. Plus, it makes for a nice drink stirrer.
The DIY mini sword was made by Inspire to Make.

I created this a few months ago. FUN. Fits perfectly in my G.I. Joe's hand (with Kung Fu grip)
