A hand planer is a woodworking tool used to smooth and shape wood surfaces. It consists of a flat base with a sharp blade that shaves off thin layers of wood as you push it along the surface. This tool is essential for achieving a flat, even finish on boards and can help create precise edges for joints. Using a hand planer requires some skill, as the pressure and angle you apply can affect the final result. Many woodworkers prefer hand planers for their control and ability to work on small projects, making them a favorite among hobbyists and professionals alike.
