Mortise Chisels

Designed with cabinetmaking in mind, not timber framing, these well-balanced Mortise Chisels are ground with parallel sides and are taller than they are wide to help keep them straight in the cut. Lie-Nielsen Mortise Chisels have Hornbeam handles. Chisels are illustrated with Heartwood Hornbeam.

Our Mortise chisels are made of A-2 Tool Steel, hardened to Rockwell 60-62, cryogenically treated and double tempered. Length ranges from 9 3/4" (smaller sizes) to 11" (1/2").

Plane maker Larry Williams requested that we make a 1/10" Mortise chisel for his work. The 1/10" mortise chisel is handy for very narrow work.

Our chisel edges are square, and parallel along the length. The backs are ground flat and finished by hand at 400 grit. The bevel is flat ground at 25º, but a higher secondary bevel of an additional 5º is advisable, depending on the wood and how the chisel is being used. Additional honing is recommended. On very hard woods, like oak, hard maple or exotic species, take lighter cuts and use a higher secondary bevel.


Lie-Nielsen Chisels have Maine-harvested Hornbeam handles. Hornbeam, also known as Ironwood, was once prized for its toughness, but usually winds up as firewood these days. This under-utilized species makes superb chisel handles.

Re-Seating Handles: When your Chisels arrive, the handles may be loose because of wood shrinkage. They may also loosen during dry weather. The handles are held in place by the wedging of the wood into the tapered socket. Just rap the chisel handle upside down to re-seat the handle (some people find loose handles annoying and prefer to glue them in).

Removing Handles: One of the advantages of the socket design is that if you want to change handles, you can simply tap the side of the handle on a board and pop the handle off.

Tool Care:


Our chisels are made of A-2 Tool Steel, hardened to Rockwell 60-62, cryogenically treated and double tempered.


Tool Steel can rust. To protect your chisels, you should oil, wax and/or wrap the tools after use. At the least, wipe your fingerprints off with an oily rag.


Materials and workmanship are guaranteed for the life of your tool. Call for repairs or replacement parts. We are available for advice if you ever have a problem using your tool.


Sharp chisels are dangerous and should be handled with care. Dull chisels are even more dangerous and should be sharpened.
