Whatsit, Whatwuzit, Whatsitgo2?
It might be from a hand tool, it might be from a power tool, it might be from just about anything and it's probably trash. But I learned a hard lesson back during the Miter Box Disaster of '09 - you don't throw ANYTHING away until 17 independent observers have certified that it is not tool related, or that you sold the related tool at last five years ago.
So at the bottom of a white plastic bucket full of yankee screwdriver bits, a broken chalk-line (covering everything else in a nice dusting of fluorescent blue), one bent carpenters square and a pile of severely rusted auger bits come this little gem. 8" long, the prongs sticking out each end are 1.5" and the one in the middle that points in the opposite direction is about 1". I'm certain it's not part of a saw jointer/filer, and that's the extent of my guesses. I could make it easy - I could take it with the next load to the dump and that would ensure that the next white bucket I pick up would contain an almost complete Blurrfl missing just this one piece, but I was never one to take the easy road. Any guesses?
Insert witty signature line here.
