A plane is a specialized tool designed for shaping wood.

It uses physical muscle power to force a sharp cutting blade across a wood surface. The primary goals of planing are to flatten timber, reduce its thickness, and create a smooth surface.

While large motorized machines can perform these tasks, hand planes remain essential for fine-scale work. Some specialized planes are even used to cut decorative mouldings or specific joints in woodworking.

The mechanism of a plane relies on the interaction between its body and a cutting edge. A plane consists of a firm body and a sharpened metal blade, often called an iron. The bottom surface of the plane is known as the sole.

A cutter extends slightly below this sole to slice off thin layers of wood called shavings. Because the sole is flat, it naturally rides on the high spots of an uneven board. As the user moves the tool, the cutter removes only these high points. After several passes, the surface becomes consistently flat and smooth.

Planes are categorized by their size and specific function. Bench planes are larger tools that usually feature a rear handle called a tote.

These often have a chipbreaker, which is a component attached to the cutting bevel. Block planes are much smaller and can be held in one hand. They lack a chipbreaker and are used for working across the grain, or end grain.

Other types include the scrub plane, which has a convex edge for rapid wood removal, and the jointer plane, which is very long for final flattening.

Woodworking history shows that planes have been used for thousands of years. The earliest known examples were discovered in Pompeii.

Roman planes, found in places like Britain and Germany, often featured an iron blade secured by a wooden wedge.

In the mid-1860s, Leonard Bailey revolutionized the tool by producing cast iron-bodied planes. His designs were later evolved by Justus Traut at Stanley Rule & Level. These Bailey and Bedrock designs serve as the foundation for most modern metal hand planes used today.

Different planes are designated by specific numbers that indicate their length. A No. 1 plane is only about five inches long. A typical smoothing plane is roughly nine inches and is often a No. 4. A jack plane is about fourteen inches, designated as a No. 5. For larger tasks, a No. 6 fore plane is eighteen inches long. Jointer planes are even larger, measuring between twenty-two and twenty-four inches, and are labeled No. 7 or No. 8.

These measurements help woodworkers choose the right tool for the scale of their project.

Specialty planes exist for highly specific woodworking tasks. A rabbet plane, or rebate plane, cuts steps or shoulders into the wood.

For cleaning out the bottom of recesses like grooves, a router plane is used.

Even tiny finger planes are used for smoothing small items like toy parts.

Some planes even use a flexible steel sole to create specific curves, known as compass planes.

Planing connects manual craftsmanship to modern industrial technology. In the past, skilled laborers performed all flattening by hand. During World War I, air-powered handheld tools were developed for shipbuilding. These tools could spin at 8,000 to 15,000 rpm, allowing one person to do the work of fifteen men. Today, electric thicknessers can reduce rough lumber to uniform dimensions on all four sides. However, the fundamental principles of the hand plane remain vital in both traditional and modern woodworking.
