A block plane is a small hand tool used in woodworking to smooth and shape the edges of wood. It features a flat base and a blade that is set at a low angle, allowing for precise control and a clean finish. Block planes are ideal for trimming end grain and making fine adjustments to the surface of wood. These tools are typically made of metal or wood and are lightweight, making them easy to handle. They are commonly used by carpenters and woodworkers, and are essential for tasks such as fitting joints and preparing surfaces for finishing.
