The Atwood FunnyBone pocket wrench features 14 tools in one handy and compact 3 1/2" OAL piece. Made of beefy 5/32" thick S30V steel these have a stonewashed finish. Wrench sizes include SAE 1/4, 5/16, 3/8, 7/16, 1/2 and 9/16. Metric sizes include 6, 8, 10, 12, 14 and 16mm. A bottle opener and additional 5/16" wrench complete this handy little keychain package. I'm tying the lanyard through the metric end but metric users can switch it to the SAE side for quick and easy differentiation.
