Teak, possibly walnut, and stainless nut crackers. You could use these for lobster or crab too. 

   Piece is in excellent condition. Stainless has some scratches and needs to be polished.  I have 2 listed separately. This one appears to have been treated with a butcher block oil and the wood is a little darker. The other one is lighter and could probably use some of that oil. Wood has some very slight nicks and scratches but overall excellent condition.

Take a good look at the photos as piece is being sold as-is.
