The rougher finish is typical of lower-class weapons of the 19th and early 20th cent., where standards of finish declined. Most of the weapons displaying this finish are simple knives or falchions of rustic character. The marks are from the hardened steel drawknives used to finish the surfaces.

On higher-grade weapons, and the surviving earlier pieces, the finish is much better, polished on stones.

As with the blades of southern India, it's hard to find older Vietnamese weapons in any sort of "polish", the humid tropical climate takes a toll on iron objects. A glance at your blade shows some irregularity in depth of the fuller which may indicate localized grinding and polish to remove previous corrosion. If the sword dates back to the 18th cent., who knows how many times it may have been cleaned, sharpened, or polished during its working life.
