Tactical Clothespin

My Residence hall is currently running a large game of assassin. For those of you unfamiliar with the game, each player is assigned a target. The player is tasked with eliminating that target from the game, after which they inherit the target's target.
In this particular game, the way you "assassinate" your target is by placing a clothespin on them.
Being an engineer, I noticed that a clothespin is not really well designed to surreptitiously attach to someones clothes. They are meant for easy removal, which is also not desirable. The jaws are shaped inefficiently, the wood slides easily, etc. So I set out to make a Tactical Clothespin.

The final design is based on an existing clothespin by Thingiverse user PolygonPusher. It has lengthened, pointed, serrated jaws to easily grab and hold onto clothing.
