Butt Mortise Plane
Our Butt Mortise Plane will help you cut neat, precise mortises for hinges, lock fronts, and strike plates in a fraction of the time it takes to set up an electric router and template.
Based on an original 1948 design by W. A. Dohmeyer, this tool does a job no other plane can do. The elongated slot in front of the blade provides a clear view of the work. It is easy to use to make precise mortises with sharply square corners to an accurate, uniform depth. Useful for mortising dutchmen to repair flaws in jambs, furniture, and doors.
- 9-5/8" long x 1-1/2" wide
- Blade is .875" wide by .115" thick
- Iron body, 1.70 lbs.

Butt Mortise Plane
This tool is easy to use and will make precise mortises with sharply square corners to an accurate, uniform depth. This plane is also useful for installation of hardware, such as hinges, lockfronts and strike plates, as well as mortising dutchmen to repair flaws in jambs, furniture and doors. This tool does a job no other plane can do.
A Scrub Blade is also available for rapid planing when large amounts of stock need to be removed, such as backplaning trim to fit an uneven wall surface.
The blade comes ready to use. Slight additional honing will increase performance. A secondary bevel
of up to 5 degrees helps achieve a razor edge quickly. This also improves edge life in hardwoods. For more information on advanced sharpening we suggest David Charlesworth’s DVD Hand
Tool Techniques Part 1: Plane Sharpening
The body is cast from Ductile Iron, a virtually unbreakable
alloy. It is 9-5/8" long and 1-1/2" wide. The blade is 3/4" wide. The
castings are fully stress-relieved, a process that removes inherent
stresses and ensures that the tool will remain flat and true. The cap is
Manganese Bronze. Other parts are Brass, Steel and Cherry.
The blade is A-2 tool steel hardened to Rockwell 60-62, cryogenically
treated and double tempered. Our heat treating technique ensures
that the blade will take and hold a very fine edge for a long time.
After heat treating, the blade is fully surface ground on the top, back,
and cutting edge, giving a smooth, flat surface that will take a mirror
finish very quickly. Wood parts are finished with wiping varnish.
Protect the body and blade from rust with a light oil.
We recommend Camellia or Jojoba Oil - vegetable oil based
products. They are non-toxic, odor-free and easy to use. Also, in
our shop, we use a fine abrasive handblock to remove any light
surface oxide from tool bodies and blades. The oils and the abrasive
handblock are available from us.
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.

Bronze and brass alloys contain lead, a chemical known to the State of California to cause cancer and birth defects, or other reproductive harm. Wash hands after handling.
