Titanium fishbone keychain bottle opener, edc multitool prybar/screwdriver, keyring/lanyard hole...

Similar to the Boker fishbone bottle opener, but slightly different.

I did try using the mouth to cut some string, but no joy. It might could be sharpened with a file.  It's hard to see the angle from the photo, but both sides do come to a center edge, as does the eye hole.
