The plane is used for the initial processing of roughly cut boards and planks, or as a follow-up after using a Scrub Plane.
Unlike the Scrub Plane, the Bench Plane does not leave uneven tracks on the surface of the wood. Its blade is straight, leaving a flat surface.
The quality of the planed area can be improved and smoothed with the Jack Plane (shaping of soft woods) or with the Smoothing Plane (medium-hard and hard woods).
The Bench Plane is one of the most universal planes used for flat surfaces.
