adze

Imagine an ancient shipbuilder carefully shaping the hull of a vessel. Or picture a skilled carpenter carving details into a wooden beam. You might see an adze at work. An adze is a hand tool with a curved blade set at right angles to a handle. It’s a bit like an axe turned sideways: instead of chopping with the blade in line with the handle, you swing it to hew or shave the surface of wood. It’s especially useful for smoothing and shaping timbers—particularly in shipbuilding and carpentry. While modern power tools have replaced it for many jobs, you can still find skilled craftspeople using adzes today, especially those dedicated to traditional building techniques.

The word "adze" (pronounced "adz") refers to both a tool and the action of using that tool. The tool itself is an ancient one—versions have been found dating back thousands of years! It consists of a curved blade, often made of iron or steel, attached at a right angle to a long handle, usually made of wood.

Unlike an axe, where the blade runs parallel to the handle to split wood, the adze has a blade set perpendicular to the handle—much like a garden hoe. Instead of splitting, the adze is swung in an arc toward the timber (and the user) to hew or shave off layers of wood. This makes it ideal for smoothing surfaces, hollowing out bowls and canoes, shaping timbers for building, and creating intricate designs. Historically, adzes were crucial for shipbuilding, allowing craftsmen to shape curved hulls with precision. They were also essential tools for constructing traditional houses in many parts of the world, particularly those built from logs.

Today, while power planers and other modern tools are common, skilled woodworkers still value the control and finesse an adze provides. You might see them used in timber framing, green woodworking (working with unseasoned wood), or by artisans creating traditional crafts.

To "adze" something is to use this tool on it—"He adzed the log until it was perfectly smooth." The word evokes a sense of patient craftsmanship and connection to ancient building traditions. So next time you see beautifully shaped wood, remember the humble adze that might have played a part in its creation!
