This is a very unique bottle opener that also doubles as a self defense weapon. The idea behind it is that it can be used as a downward "slashing" weapon in the event that you need it for self defense.
As you can see in the pictures below it has an "edge" to it, while the edge is not sharp enough to cut you if you run it over your hand. However when used in a slashing motion it is sure to put the hurt on an attacker.
I have seen quite a few people say on his Instagram pictures that it looks like the de-cap-aturtle would fold over if you hit someone with it, but after getting my hands on this one I can tell you it is a solid piece of work. It is made from 1/4" thick 6061 aluminum and the craftsmanship is awesome. Also since it is made of aluminum it is very light (.74 ounces) and I hardly even notice that it is on the keychain.
It also makes for a good bottle opener, the first time I used it to open up a beer it literally bent the cap in half.
