Been thinking about this one awhile, and after getting to meet Jimmy DiResta at Maker Faire (Bay Area 2016) I was finally inspired to get it done.   The pick is an old screwdriver, the handle is an old motorcycle chain, and the clasp is a shackle bolt.  I’m amazed at how useful it actually is.  I found myself using it even before it was finished being built, and when close it still works as a screw driver.
