Kezuriki

Kezuriki

Kezuriki is a traditional Japanese woodworking tool used for planing wood. It is commonly known as a Japanese hand plane or a wooden plane. The word "kezuriki" is derived from the Japanese words "kezuru" (to plane) and "ki" (wood).

History

The history of kezuriki can be traced back to ancient Japan, where it was developed as a tool for shaping and smoothing wooden surfaces. The earliest known examples of kezuriki date back to the Nara period (710-794 AD). Over the centuries, the design and construction of kezuriki have evolved, but the basic principles have remained the same.

Design and Construction

A kezuriki consists of a wooden body, a blade, and a chipbreaker. The body is usually made from a single piece of hardwood, such as Japanese white oak or cherry. It is carefully shaped and smoothed to provide a comfortable grip and a stable platform for planing.

The blade, known as a "kanna," is made from high-carbon steel and is extremely sharp. It is inserted into a slot in the body and secured with a wedge. The angle of the blade can be adjusted to control the depth and angle of the cut.

The chipbreaker, or "uragane," is a thin piece of metal that is positioned just in front of the blade. Its purpose is to break the wood fibers and prevent tear-out, resulting in a smoother finish.

Usage

To use a kezuriki, the woodworker holds the body with one hand and applies downward pressure while pushing the tool forward. The blade slices off a thin layer of wood, leaving a smooth surface behind. The woodworker can adjust the depth of the cut by tapping the back of the kezuriki with a wooden mallet.

Kezuriki is commonly used in traditional Japanese woodworking techniques, such as making furniture, joinery, and decorative items. It is also used by artisans and craftsmen who specialize in traditional Japanese carpentry.

Maintenance

Proper maintenance is essential to keep a kezuriki in good working condition. After each use, the blade should be cleaned and oiled to prevent rust. The blade should also be periodically sharpened to maintain its cutting edge. The body of the kezuriki can be treated with a protective finish, such as oil or wax, to prevent moisture damage.
