These chisels are made from blue steel in the Sanjo region of Japan. They are blacksmith made chisels and come ready sharpened.
The high carbon-steel edge guarantees perfect sharpness and precision and is backed by a body of softer iron – a perfect ‘shock absorber’. This backing iron is “folded” and then etched in acid to reveal the distinctive damascas pattern which is particularly attractive in the wider chisels.
