Where did the idea of an adjustable spanner initiate from?
JP started his company, Enköpings Mekaniska Verkstad, in Sweden in . He always had a set of pipe wrenches to hand in his workshop. Each wrench fitted a particular size of pipe, but this meant having to carry around a variety of sizes. This is where his idea of an adjustable pipe wrench sprung to mind. He designed it so that its jaws could be easily adjusted to fit all pipes, irrespective of size. The pipe wrench is now known and sold worldwide.

Similar to pipe wrenches, JP realised that nuts and bolts, too, required different sizes of tool to tighten and loosen them. His idea of an adjustable spanner came to light and would bring him worldwide fame in years to come. However, he was not the original inventor of the adjustable spanner. The first one was created by Joseph Stubs, 50 years earlier. JP improved the original tool design by giving it only one moveable jaw and it was sold and loved all over the world ever since.
In , JP handed over his business to his son, Hannes and Berndt August Hjort, so he could focus on his inventions. The company then became Bahco, who are one of the market leaders in hand tools and have produced over 100 million adjustable spanners to date. Toolstop stocks a full range of Bahco adjustable spanners.
Since the introduction of the original Crescent wrench in the early s, the Crescent brand has become synonymous with adjustable wrenches. Crescent Adjustable Wrenches feature a large knurl for easy adjustment and a tight jaw fit. Its hex jaw design helps reduce slippage and tightly grips the fastener for solid, secure operation, while the corrosion-resistant chrome finish helps prevent rusting. A wide handle design provides comfort and reduces fatigue during extended use. The Crescent adjustable wrenches are ideal for both pros and do-it-yourself enthusiasts.
