Futo Grinders are unique because they are CNC machined from solid exotic wood - the teeth are strong thick slabs of the right exotics with the grain running in the direction of the teeth, so they're not just attached or pinned in like the cheap imports - they're integral carved from the solid wood. Use of a thick diamond shaped tooth layout that gets excellent reviews.. Original 2 piece grinders are held together with strong rare earth magnets. The wood does well to resist sticky build up, it's finished with an all natural food safe organic beeswax and oil wood finish. No aluminum dust from wear and grinding, no tight metal connections that can clog, a simple functional design made from all natural wood.
