‘old’ files and rasps were always made with high carbon steel and were hardened after preparing their surfaces. This meant they were ‘soft’ enough to cut the grooves into at the start, and then hardened so those grooves would last. This makes these old files fantastic to use for knives.

And if you grind the bevels in just right you can leave an awesome pattern as well.

Blade length is approx 22cm depending on the length of the starting file. If necessary a handle will be added to maximise blade length. Will be coffee etched to create a protective oxide layer.

Dishwasher safe!
