I will be displaying a range of unusual wrenches, from the 18th c. to the early 20th c. at the Mercer Museum in Doylestown, PA, 2 - 4 P.M. next Saturday, August 20th.
I will be making the "case" for the role of creativity in the design of each wrench, even though it was always designed, from at least Roman times forward, for a single function: turning a threaded object resting snugly inside/outside another threaded object.
