The sharp blades are sharpened on both sides so that both sides can be used by turning them over. The planing knife, made of particularly fine-grained carbide, has an extremely sharp cutting edge, with which consistently fine and even surfaces are achieved. Fine-grained tungsten carbide is also highly wear-resistant. It is insensitive to damage or breakage due to accidental contact with nails or staples, so that a long service life is possible. This durable blade is suitable for many planing applications, such as planing, thickness planing and chamfering as well as rebating in hardwood, softwood and wood composites. The Wood Razor carbide reversible planing knife also allows quick and easy blade replacement and effortless, perfect positioning.
