Hi All,
I haven't seen a lot of weapons confidently sourced to Micronesia, except for the shark-tooth weapons of Kiribati.  Then I tripped over a 1982 
Black Belt Magazine article on the martial arts of the Caroline Islands aka pwang or bwang.  
(link to article).
Interesting thing is that they use a distinctive, short (3-4'), heavy, double-headed wooden spear called a Pochoch as a central weapon.  The spears are used hand-to-hand, either on land or in canoes.
I've never seen these before (although I've seen double-ended spears before).  Does anyone have a physical example of a pochoch, or know of one in a collection?
Best,
F
