Made with the finest Japanese carbide blade, it boasts sharp sharpness and exceptional durability. Easily divide 1.5-10mm thick sheet glass or burner rods. Since it is a round blade, if the blade gets worn, you can use a hex wrench to loosen the screw and rotate it to use a new part. Specifically, it can be used for decorating the edges of plate glass, cutting parts and making frits by cutting edge glass. The blade is highly durable as shown above, but not guarantees permanent sharpness. We recommend replacing the blade if you feel that all parts of the blade are poorly sharp.
