For "terciado".

Since it's explicitly scimitar-like, it doesn't sound like a kampilan to me. If it's similar to modern Philippine weapons, a big pira or a panabas? But long curved swords were not unusual in the area - a classic weapon of "Japanese" pirates. A long dao/dha/katana-like sword could be described as "like a scimitar, but larger".

Timo, we cross posted and I just saw your outstanding links and superb assessment, which describe what I was trying to say perfectly! Thank you!
The term 'scimitar' is a classic example of this kind of dilemma......rather than being an exact weapon form, it is a 'description' and most commonly found in literary parlance. Excellent!
