Gerber EAB pocket knife keyring holder

This thing is for the [EAB folding pocket knife from Gerber](http://www.gerbergear.com/Knives/Folding/EAB-Pocket-Knife_22-41830).

The knife itself is an incredible value, first for the fact that the blade is interchangeable, because it uses standard razor blades, which are the go-to blades for a lot of applications. The knife is sturdy, slim, easy to use and very safe too, since the blade is protected where it needs to be.However, it's a paperclip kind of folding knife. Meaning there's no hole to put in a keyring. This would be fine if the blade retension was good enough to not let the blade open on its own in your pocket, however, the groove for the little ball that holds the blade closed is not deep enough, so it's very easy to open the blade by accident.

This is the reason why I made this. It allows the knife to rest in closed position, with walls all around it to keep it from opening on its own, and a small hole allows for a keyring to be added.
