Sangkuh related to Sangkoh?
 

A while back their was a discusion on a weapon perhaps designed off a bayonet known as a sangkuh. Recently I was looking through Traditional weapons of the indonesian archipeligo and found a weapon used by the Kalimantan, Sea dayaks known as a Sangkoh, could these two weapons be related? Now I know that book doesn't have perfect information but is there a possible connection? It says the sangkoh is a thrusting blade used in close quarters. Sounds to me how i would of used a Sangkuh. Does anyone know how sangkoh is prononounced? does anyone have one?
Sincerely,
Eli
P.S. Their is some breif information on how the Sangkoh looks if you would like to know.

They don't seem to be related to each other.
Sangkoh is a long spear with flat spear head according to van Z, Ling Roth etc.
Sangkuh is a short weapon, shaped like a triangular bayonet, as you described.
