This grinder by Santa Cruz Shredder are much gentler than standard grinders. The unique shape of its teeth help to shred, rather than crush and damage your dry leaf blend. They are constructed from medical-grade anodized aluminum and have a textured edge for a more comfortable grip. A rare earth magnet secures the top and keeps the pieces together. This 3 piece medium (2") grey model grinder not only has your standard Santa Cruz Shredder but also a second compartment that catches everything that drops though. It is available now at the Coughing Cardinal.
