Wooden grinders for cannabis or tobacco. These grinders are all made of wood, or faux wood designs to give a classic old-school feel. These wooden grinders generally still use metal or aluminum teeth to grind up the flower easily, and some even have full metal frames with a wooden shell. We have sharp teethed wooden grinders as well as simple cheap wooden grinders available for sale! Some wood grinders have designs etched in or printed on top, for those seeing something less plain.
