Is Crescent really the original inventor of the adjustable wrench?

Yes we are! In 1907 Swedish immigrant and inventor Karl Peterson founded the Crescent Tool Company. Soon after that he introduced America's first open-end adjustable wrench a revolutionary concept that replaced an entire set of dedicated-size wrenches

- Wider jaw capacity than traditional pipe wrenches
- Slim profile head design allows better access to tight areas
- Heat-treated forged alloy steel for toughness and durability
- Strong I-beam handle construction
