You would think that with my collection of purchased and inherited tools and overall tool hang-up, I would have at least seen one of these before. I have some old Craftsman double-ended ratchet wrenches that are dog-bone shaped, but this version is new to me; I don’t know how I overlooked this.
Sears has their DOG BONE wrench in both SAE and metric for $20 each. Thorsen seems to have an equivalent for $15, although their version does not have the all upper-case name.
This could either be super handy to have around, sparing you trips back and forth to the tool box to find the right socket — or the bone ends would get in the way left, right, and backwards.
