We've been working with steel in Sheffield since 1730. Our heritage is extremely important to us, because it's our experience which makes our tools some of the very best you can buy.
Find out more about our long history, and what makes our tools so special.

Adding carbon to steel gives strength, adding chromium brings rust resistance. But it’s a trade-off; our steel cannot be high carbon and high chromium, so we make sure we get the right steel composition for each part of the tool.
A single hand fork contains three different compositions of steel:
-
1Ferrule
High chromium/low carbon. Why? It starts life as a disc, so we don’t want this to be too hard because we want to shape it. It doesn’t need strength for its end function. -
2Tang
Medium chromium/medium carbon. Why? It needs to be strong to resist bending, but is also made from quite thick material to give good levels of inherent strength. -
3Tines
Low chromium/maximal carbon. Why? Tines are the weakest part of the tool, yet need maximum strength and hardness to resist bending in the ground.



But we don’t stop there. Rigorous testing gives complete peace of mind; every batch of tools is tested against the British Standard, which determines the weight the tools must be able to withstand without permanent deformation.
And if ever a batch were to fail… we wouldn’t sell it.
