Model Maker's Block Plane

Our Model Maker's Block Plane is a miniature workhorse that will fit in some tight situations better than any other Block Plane. This delightful, small low-angle tool fits snugly in the palm of your hand, and is ideal for all sorts of chamfering and trimming jobs.


The blade is bedded at 12°, making the included cutting angle 37°. Blade comes with a 25° flat ground bevel.

Blade Sharpening:

The blade comes ready to use, but honing a secondary bevel of 5° or 10° will increase performance, help achieve a razor edge quickly, and improve edge life in hardwoods. You can find sharpening instructions in a printable PDF format here:

For more information on advanced sharpening we recommend David Charlesworth’s video Plane Sharpening, available in both DVD and streaming formats.

Blade Adjustment:

Slightly loosen the pressure of the cap and advance or retract the blade. Tighten the thumbscrew. Do not overtighten. You should be able to adjust the blade after loosening the spinwheel about a quarter turn.


We use Ductile Iron for the bodies. These 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.

The blade is A2 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. The 1/8" thickness provides solid, chatter-free cutting.


The body casting is ground flat and true (to .0015"). Occasional hand lapping with fine wet/dry sandpaper (400 grit or higher) on a flat surface will help remove dings and keep it true. The cap iron can be polished with any good brass polish, or allowed to patina with age and use. Occasionally, the tool should be disassembled, cleaned, and moving parts oiled. The blade should be kept lightly oiled to prevent rust, especially when the tool is not in use. We recommend Jojoba Oil, a plant based oil product that is 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. Jojoba Oil and abrasive handblocks are available from us.
