Pocket-Sized Crescent Wrenches

Joe Greiwe's collection centers around the 4-inch adjustable wrench.

A historic group. From the top: The first Bahco adjustable wrench patented and produced; an 8-inch Bahco “Jubilee” wrench celebrating the 100 millionth Bahco wrench produced, and the modern-day production adjustable wrench. Below: A “double ender,” with a 4-inch head on one end, and a 6-inch head on the other. Right: An example of a wrench with a worm lock.
