The purpleheart black slate is what started S.T.D Turkey Calls 
And still my favorite call
So i added ceramic surface to the purpleheart pot gave it a thick glass soundboard.. it's a hybrid of the black slate.. call soft on it or get loud.. this call does all the sounds you want out of a call.. comes with a purpleheart 1pc striker..
