The screwy thing about this ring is...literal. And only literal, because the Screwdriver Ring isn't weird or messed up at all. It's awesome!
A simple stainless steel ring machined with a Phillips head protrusion, Yetch's Screwdriver Ring is fully functional, though meant for light use only if you don't want to scratch it up. Puncturing an orange to peel like the dude in one of the photos above seems like a pretty safe bet.
