My blades and cutters are superior to the originals and will perform better. I start with high carbon industrial grade precision ground flat stock. For consistency and quality, all of my products are professionally heat treated to my specifications. They are harder than the originals so they hold their edges longer. Many of my products are also thicker than the originals. All of these characteristics are proven by my shop testing and they provide woodworkers worldwide with superior cutters for their woodworking planes.
