Turned and milled from O1 tool steel (HRC 58-60), chosen for its ease of sharpening and good edge retention at low bevel angles. Each chisel has superb balance, with the centre of gravity at or below the tang/socket connection. The blades taper from shoulder to tip for strength and rigidity. Parallel sides and true bevel edges give full clearance when working into a corner. Lapping to a flatness of ±0.0127mm (0.0005") or better over the entire surface ensures the face of the blade is smooth and true. The blade-to-handle connection is similar to the Japanese, with a tang and a socket-like ferrule. The tang has flats to prevent the handle from rotating. Repeated mallet blows will only tighten the joint. Kiln baking the hard maple handle at a high temperature eliminates nearly all the moisture content and caramelises the natural sugars in the wood. This imparts a rich, dark colour, while helping to seal it against humidity changes. The handle has shallow flats parallel to the blade back. 1/4” chisels has a 30° primary bevel angles, 2° micro bevel and requires only final honing before use. Made in Canada.
