Description
Peudeueng is the Acehnese variety of the word pedang which simply means sword. In north Sumatra, it is usually applied for the curved saber of foreign origin or local copies of such sabers.1
Acehnese peudeueng often come with basket hilts, called hulu meu apet. These were strongly inspired by Indian basket hilts of similar form. They were expensive and usually carried as a sign of rank and status.
Some collectors call them peudeueng peusangan, the last word meaning "curved".
