What a colorful type of wood. This is Honey Locust. Very Hard but something special to look at. This mill as well as the others I make will grind Salt, Pepper, or Spices. I include a LIFETIME GUARANTEE on the mechanism in my mills. If it should stop working properly send it back and I will replace it. Free of charge. If you prefer a different wood please ask. I have over 150 different woods and more than 100 different burls.
