In my opinion it appears to be an object made in the tradition of classic Native American war clubs (mainly used before tomahawks with steel blades) - the leather doesn't show significant signs of wear.

length is 44.5 cm

The object was once bought at an Estate Auction in Germany - I don't have any information on previous ownership or how the war club came to Germany.

object shipped from Austria - shipping to the US and within Europe is 18 USD (other destinations according to shipping rate of the Austrian Post)
