one thing to consider on the indonesian weapons, like pedangs and keris, the owners would frequently change their 'clothes', gold, silver, suasa, jewels would come and go (to the money lender) as their fortunes ebbed and flowed. the blades were what was important, the clothes, like ours were to honour and compliment the blade and could be changed for important occasions to more expensive scabbards, grips, bolsters (mendak), scabbard covers, etc.
in thailand and burmah, it was the other way round, the fittings were what showed your status, the blade was of lesser importance for the average person and many are quite roughly finished. the decorated ones with good grips (and matching scabbards) are for quite important ranking people and were generally permanently mounted together with cutler's cement, unlike keris and pedangs which normally are a press fit with a wrap of cloth (or hair) around a round tang to make it fit the oversized hole in the grip & no cement).
the dyaks ornamented everything, grip (cemented on), blade, scabbard, their own clothes, hats, and themselves,
