Whereas the pisau raut is intended as a tool but could be used as a weapon (most anything with an edge can) , I'm really not sure if the toa is a combination axe / weapon .
Given the weight and size of the blade and the two handed grip the toa would be a most efficient weapon and a good jungle axe too ; very much like the panabas .
My example is 34.5 inches overall with 20 inches of haft and 14.5 inches of heavy blade .
Okay , I've been through Van Zonneveld's Traditional Weapons and after reading his description of the toa I get the impression that it is a fighting sword from his text .
He also notes that most toas have a horn ferrule with metal being the rare exception ; IMO horn would not stand up very well to use on hard materials such as wood but it would be acceptable if used on softer materials like one's fellow man .
