I kinda hope this doesn't end up in the dustbin of 'widgets that were actually innovative but never made very well and not useful enough to replace tried-and-true tools'. A keychain version with 1/4 and 5/16 wrenches would be neat.
LeoangerWhat would you ever practically use that for that warrants carrying it on a keychain? It's not innovative in any way, it's a solution searching for a problem.
CatpantsI come across 1/4" and 5/16" hex screw heads and 5/16" nuts/bolts often enough that such a back-up tool would get used if I always had it on me. And if it could securely hold a driver bit, the usefulness would be extended. This tool is innovative by virtue of its compactness.
