While going through tools, we noticed significant differences in P&C wrenches which prompted us to post them in this manner. The longest wrench here is 13 1/2" long, and the shortest is approximately 13". Each wrench is approximately 1/8" shorter than the next longer wrench. Three bear the circle-R trademark symbol, and two are stamped USA. We assume the 2 non-USA stamped wrenches were made in Canada.
