Chinese (or other country) sai/parrying weapon

[josh stout]

The top one I posted is from an area of Northern Sumatra where Chinese laborers were brought by the British in the late 19th c. The set of two and the other one with a wooden handle are all Chinese. All three are octagonal. The set with brass guards and pommel has a scoring line accentuating the rounded points. The other wooden handled Chinese example has a flat tip. The Sumatran one looks exactly like the other Indonesian examples shown.
