Santa Cruz Shredder has been engineered to perfection. After carefully analyzing how a proper tooth design should work, SCS used a high-end computer machining software to invent THE PERFECT shredding tooth design ever conceived by man! Their teeth are a radius at the base for strength and can take extreme use. They’re twice as strong, will never dull, and never release burrs or flakes of aluminum. Comparable grinders cut once – letting bb-sized chunks pass through the holes without further grinding. SCS’s teeth were designed to cut multiple ways, which include clearances on both sides of the teeth (not to slice or smash herb), but to cause it to consistently “FLUFF TO PERFECTION.” You will never need another grinder, just a Santa Cruz Shredder.
