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)
Ended up having to use this recently to disassemble a lock that wasn't functioning correctly, alas the lock issue was not resolved but the flathead worked well for prying and the Phillips handled all the screws wonderfully. The loss of a star 🌟 is only because the anodizing appears to rub/scrape off if the drivers are used in tight spaces but the tips appear hardened and haven't rounded off yet.
It is compact and versatile. If you find your grip a bit weak to turn it and break loose, it will let you attach a ratchet (not included) to help.
Each of the 7 people to whom I gave one of these was thrilled.
