Definition & Meaning of "jointer plane"

What is a "jointer plane"?

A jointer plane is a hand tool used in woodworking to create flat, smooth surfaces and straight edges on wood. It has a long, flat body with a sharp blade that cuts thin shavings from the wood as it is pushed along the surface. Jointer planes are especially useful for flattening rough boards or ensuring the edges are straight and square, making them ideal for preparing wood for joining or assembly. They are often used when working with hardwoods or when fine control over the flatness and alignment of the wood is required.
