Set of 10 Japanese blue steel mini chisels with white oak handles
A very nice set of chisels for all small jobs. The slightly different alloy additives from those used in white paper steel improve the edge retention of blue paper steel chisels and make for a tougher edge that is less prone to chipping. The achievable sharpness is slightly less, but for most practical purposes this should not make any difference.

The chisels are not sold individually. They come in a kiri wood box with a polystyrene lining to protect the cutting edges.

MATSUMURA Namaji Oire Nomi
These Japanese chisels are made of readily sharpened white paper steel. The laminated blades have a backing layer of Namaji, vintage iron repurposed from 19th century railway tracks whose properties further improve the sharpenability of the cutting layer. Namaji is difficult to forge and only a few, very experienced blacksmiths have mastered this technique. Namaji is soft and easy to polish. The handle is made of sandalwood. The overall length is approx. 220 mm. Because the chisels are forged by hand, their lengths may vary slightly.
