Santa Cruz Shredder is engineered to perfection. After carefully analyzing the inner working of how a proper tooth design should work, we used a special computer program called Siemens CAD Software to invent the most ”perfect” shredding tooth design ever conceived by man! Sharp-edged teeth are not the best approach… Sharp-edged teeth will dull and are full of burrs & tiny flakes of aluminum – constantly falling into your smoking blend. This is not only unhealthy, but toxic to the consumer. First, sharp edged teeth take a lot of initial torque to start turning. This initial pressure will force it to bend at the base, causing “metal fatigue” resulting in the eventual breakage of the tooth and releasing even more flakes of aluminum into your blend. Our teeth are radius at the base for strength and are able to 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. Our teeth are 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“
