Japanese Chisels

About

Japanese Chisels for Fine Joinery and Precision Woodworking Japanese chisels, commonly known as nomi, are traditional woodworking tools designed for accurate cutting, paring and joinery. They are widely used for tasks such as fitting mortise and tenon joints, cleaning dovetails, trimming shoulders and refining detailed cabinetmaking work. Japanese chisel designs typically combine a hard cutting edge with a tougher supporting layer of steel, creating a blade capable of taking a keen edge while retaining the resilience required for woodworking. There are several styles of Japanese woodworking chisels suited to different tasks. Oire nomi are relatively compact bench chisels used for general joinery, while longer or heavier chisel patterns can be suited to deeper mortising, timber framing and specialised work. Japanese chisels often require some preparation before their first serious use. Depending on the individual tool, this can include checking and flattening the back near the cutting edge, sharpening the bevel and correctly setting the metal hoop found on many traditional handles. The hollow-ground area commonly seen on the back of Japanese chisels, known as the ura, reduces the amount of steel that needs to be removed during flattening and sharpening. The narrow flat land immediately behind the cutting edge should be maintained rather than grinding away the hollow unnecessarily. FAQs What is a Japanese chisel? A Japanese chisel, or nomi, is a woodworking chisel traditionally constructed with a very hard cutting-steel layer supported by a tougher, softer steel body. This laminated construction allows the cutting edge to be hardened for good edge retention while the supporting material provides greater toughness. Designs vary according to whether the chisel is intended for bench work, mortising, paring, carving or timber framing. What are Japanese chisels used for? Japanese chisels can perform many of the same woodworking operations as other quality chisels, includin
