"Heavily corroded and has a pleasing oxidized appearance" Now that's spin

I gotta remember that one; I've got some things with real pleasing appearances

The sword formerly known as Tempius

a big one, too; cool.
The parang nabur type hilt (and note that that is an "Eastern" knucklebow; the type that went TO Europe) is sometimes seen on these. Collectors' tale is it was favoured by professional soldiers (though they're usually referred to as "guardsmen"). Seen 'em with knucklebows full and partial, as well as with knuckle chains, and some of the mountings said to be quite old.
Interestingly, the plainer, more common (note I hesitate to say older or more traditional, though in some sense it probably is) handle, which swells out to match the width of the blade base, often has a ferule which extends to form a "drip guard" or sheath lid.
