Briggs & Stratton Oil Cap Tool

Neat tool but ...

It works better than an allen wrench or offset screwdriver but the square hole for the ratchet isn't exactly square. It looks like they drilled a round hole then ran a square broach to make 4 V notches for the corners. Being made of aluminum, I expect it will strip out pretty quick. I'd have preferred steel but since most plugs are plastic the aluminum should work. Maybe milling a hex on the outside of the tool would be better. Then you could use a standard hex socket. Good idea but it could've been implemented better.
