I think in the later part of the keris evolution, it is not so much a weapon as a part of the dress code.

I don't recall seeing many long swords in Kelantan, but that does not mean there isn't any. Maybe I'm just not meeting the people who collects them, but the most common bladed types I've see are keris, badik, golok, kapak (axe), parang and klewang (both curved types). Don't recall many long swords.
