This is made from Circassian Walnut from Turkey. It is a rare and expensive usually saved for the finest gunstocks. I have purchased several pieces of this wood exclusively for pepper mills I make. This one has been sold but I can make you one of redesign a special one just for you. I give a "Lifetime Guarantee" on my mechanisms. I use only eramic grinders so this will grind Salt, Pepper, or Spices.
