The simple concept of a screw driver on your key ring is not new. Nobody has made a high quality key ring screwdriver for the last 10 years, until now. They are constructed of heat treated, blackened steel.
They are so simple, there's not much more to say about them.
(One Phillips and One Straight Blade)
Sturdy, the right size for on the go. I liked them so much, I went back and bought another set.
Appears to have a heavy phosphate coating and made of quality steel. Much better than the ebay Chi Comm junk
