Push chisels are driven by hand for paring cuts and fine fitting of joints. Produced with great care and attention to detail, these are hand forged at Koyamaichi Blade Works, a family-owned business that has made reliable, practical woodworking tools for over a century.
The handle of these cranked-neck chisels (kotenomi or "trowel chisels" in Japanese) has a 40mm offset (about 1 1/2") that gives excellent clearance for working in deep recesses, such as dadoes and sliding dovetail housings. The short blade and sharply angled neck allow good access and maneuverability in tight spaces, and the blade has a triangular cross section that allows work adjacent to angled shoulders.
They have laminated blades that combine a high-carbon Yasuki white steel face (hardened to Rc65-66) with a softer steel back for strength. The long red oak handles offer comfortable grip and improve control; they are canted for surface clearance. The tapered, socket-like ferrules reinforce the blade-to-handle connection.
As these chisels are hand forged, they may vary in size by ±1mm. Approximate Imperial sizes listed in brackets.
