They use American-made diamond-honed tungsten carbide, which is engineered for fast, consistent sharpening and extended durability. The blades are reversible, effectively doubling their usable life, and most users report 5–10 years of service life per set, depending on use frequency and pressure.
They are compatible with all models in the system except ShearSharp®, meaning they’re intended as universal replacement inserts for standard carbide pull-through sharpeners in the range.
