Small Router Plane - Closed Throat Lie-Nielsen Toolworks

Small Router Plane - Closed Throat



No. 271 Small Router Plane - Closed Throat

Loosely based on the Stanley No. 271, these small Router Planes are perfect for shallow mortise and small relief work. The compact design makes it easy to guide along narrow edges and fit into tight spaces.

We make both Open and Closed throat versions of our Small Router Planes. The Open Throat design offers more visibility in front of the tool, which is especially useful for inlay work. The Closed Throat design gives more support in front of the blade, making it ideal for working on the edges of boards or cleaning out the end of a stopped groove in a rail or stile.

Our Router Planes have square blades, held solidly in square broached holes. This prevents the blade from slipping or twisting when removing large shavings or during diagonal use. The blade can also be mounted to face the back of the plane to work closer into corners.

  • 4" long x 2" wide
  • O1 blade with 1/4" wide square tip
  • Iron body, .55 lbs.

For inlay work, we offer an optional 3/32" square tipped blade, and 1/4" and 3/32" pointed blades.

Small Router Planes

Our router planes are loosely based on Stanley models, but many revisions of router planes have been made over the years. All derive from the traditional, wood-bodied routers often referred to as the old woman’s tooth.

The closed throat design gives more support across in front of the blade, making it ideal for working on the edges of boards or cleaning out the end of a stopped groove. The open throat design makes it easy to see what you are doing. Sometimes, as when working a narrow edge, this can be a drawback. A good solution for this is to tape or screw a piece of wood or MDF to the base.


The blade comes ready to use. Slight additional honing will increase performance.

First, hone the bottom of the blade. Make several passes along a waterstone until a slight burr is formed along the cutting edge.

Then flip the blade over and make a few light passes along the beveled face to remove the burr.

Blade Adjustment:

Advance the depth of cut as you work. Loosen the lock screw and advance the blade with the adjuster nut. Take as thick a shaving as you comfortably can.


Additional blades for our Small Router Plane are available and can be used in the Large Router Plane with the Router Plane Blade Adapter.

We also offer an optional Depth Stop for the Small Router Planes.


The body is cast from Ductile Iron, a very strong alloy that will take a lot of abuse. These castings are fully stress-relieved, a process that removes inherent stresses and ensures that the tool will remain flat and true. Other parts are Brass.

The blade is O1 tool steel, hardened and tempered to Rockwell 60-62. Our heat treating technique ensures that the blade will take and hold a very fine edge for a long time.


Occasionally, the tool should be disassembled, cleaned, and moving parts oiled. The blade should be kept lightly oiled to prevent rust, especially when tool is not in use. Waxing or oiling the body will help protect it from rust. 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.
