i assume you meant the taiaha, i was thinking of it as i bid on this one.
they are generally in the range of 1.5 metres, depending in the maker's and/or user's whim & do not have wrapped grips the grip areas are slightly oval. i have two, a lightweight carved blade pine decorator, and a heavy hardwood 'user' -it's twice the weight of the pine one in the same length. (below, top is the display one, 2nd the 'user')
the taiaha has the two-faced tiki with the protruding tongue as a pommel. there is also a even more similar club to the solomon one, the Pouwhenua (bottom), that has a sharp point instead of the tiki. the taiaha mainly uses the blade end for striking, tho the pointy end can be used -it is not sharply pointed but would still do damage. the pouwhenua however is used to both strike with the blade and the sharp point. (the pouwhenua is not mine, i'm still looking for one i can afford. they cost more.
