OSTER 4-Point Wide Diamond Cutter

Home » Our Products » OSTER 4-Point Wide Diamond Cutter


All of Oster® blades are put through a twelve step process guaranteeing quality and craftsmanship. We start with a fine grain carbon steel that is heat treated to create a hard surface for greater wear resistance, leveraging a Rockwell hardness rating of 62. Patented Cryogen-X™ process takes the blades down to a 300 deg for a deep freeze, producing a harder, sharper blade which extends the product life. Each blade is then hand lapped for a smooth cut finish.
