I have been lucky to acquire another Wayana club. Which prompted more searching for information on the form. Finally I used the right wording and found all I need in a dissertation from Florida University for a doctorate.
The club is known as a Kapalu carried by chief/shaman important enough to be carried on the shoulder of a minion to event of use. It is a war club but ceremonial representing awesome power not unlike nuclear weapons in our minds. The spike end is used to support the club upright in the grouned by the hammock of the chief. The real use of these and war clubs has more or less ended at the close of the 20th century. The link has so much information. The most relevant pages are 372-374 for greater learning.
The new acquisition is the dark painted example. From the shipping cost I think it is made from a soft light wood which is usual, the other example is a heavy hard wood. Lesser quality versions are made as trade items.
