Sangkuh related to Sangkoh?

[eli]

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.
