Parang, Pedang or what?

[A. G. Maisey]

In Jawa just about all ferric weaponry --- and a whole heap of other things --- is cleaned with acid. In other places the cleaning is done mechanically, more often than not with wet sand. The result of a mechanical clean is a more or less polished surface. Sometimes after the clean with sand or whatever, the blade will be stained, sometimes not.

This blade looks perfectly OK to me.
