Bahco gave this ordinary adjustable wrench a secret double life, by adding some teeth to the unused side of its sliding jaw. With one smooth side and one serrated side, you can use the adjustable wrench as you always have — or reverse the sliding jaw and grip some pipes.
To convert from normal wrench to pipe wrench and back again, spin the sliding jaw all the way off with the thumbscrew, and turn it around. The only disadvantage to this process: You could lose the sliding jaw, since it’s removable.
Bahco makes this wrench in many styles: black phosphate, chrome, and with or without ergonomic grip. They sell the wrench in 6″, 8″, 10″, and 12″ versions. Depending on size and finish, you’ll probably pay around $25 to $35 for one of these reversible adjustable wrenches.
