So i'm guessing (because your post was really vague) that you're looking to buy one? If not the black rubber kind, looking for a leather head maybe? Details guy! What is your price range? Are you ok with rubber as long as its different from the mandrake head?
I have one from high density foam, i think that's what you're looking for. Ill post a picture tomorrow. I bought it at Pennsic, there's maybe 10-15 different designs, about ~15$ each.
