CoJang and rudus(?)

[werecow]

I was wondering about the distinction between the rudus and cojang.

I've had the less fancy of the two swords below for a while. I assume that that one is a cojang. 77 cm overall with a 62.5 cm blade, 4.8cm max width, 9mm thick at the hilt, 499 grams. On a side note: Apparently this one was used in a theater production (together with a very banged up sikin panjang)! It's a very light blade. No decorations. Faint signs of laminations but it's hard to tell.

The bigger, heftier, fancier one with the nice laminated blade is one I just picked up from a local auction house. Early birthday present from me to me. 82 cm overall, 62 cm blade, 5.7cm max width, 11mm thick at the hilt, 649 grams. As you can tell from the measurements the blade is actually a little shorter but quite a bit wider and thicker. Much more substantial hilt with decorations and a reinforcing ferrule. Clear laminations and decorations on the spine and "greneng" before the cutting portion of the blade.

Is this new one a rudus? I've been a little unclear on what exactly distinguishes the two visually if not the stalk at the end of the grip and maybe the cant of that grip.


Since this one has so many names, I'll add the search terms: Rudus, CoJang, Cot Jang, Gliwang, Tjot Jang, Klewang Cok Jang, Klewang Tjok Jang, Klewang Tjok Jang, Tjo Jang, Tjok Ilang, Tjok Jang, Tioq Jang, Tjot Jang, Aceh, Atjeh, Malay, Sumatra
