Woodworking straight knives and bottom cleaning knives are two different types of woodworking tools, with their main differences being their purpose and blade shape.
Woodworking straight knife is a common woodworking tool, mainly used for cutting wood, planing wooden boards, removing burrs, and polishing wood. The blade of a woodworking straight knife is a straight edge with a wide blade, generally 3-4cm, suitable for cutting and polishing large areas of wood.
A bottom cleaning knife is a professional woodworking tool mainly used to remove unevenness on the surface of wood, correct brown scratches or cuts, and make the surface of wood smooth and even. The cutting edge of the bottom cleaning knife is curved and narrow, usually 1-2cm, suitable for cleaning and trimming small areas of wood.
Therefore, although both woodworking straight knives and bottom cleaning knives belong to woodworking cutting tools, their usage scenarios and blade shapes are different, and suitable cutting tools need to be selected according to specific woodworking tasks.
