It is used on this site
http://www.perak.gov.my/sultan/english/sundang.htm to describe a sword that has a hilt resembling an Aceh Peudeung with a Hulu Meu Apet ( but with a narrower straight blade not a curving one). The last two swords also have hilts that resemble the Hulu Meu Apet or khanda. I am sorry I have no more pictures of these right now. In the article it is also seems to be spelled "Cutum"
The picture caption is
Sword Kris Curam, Si Raja Wali, Sundang and Sada Maikah.
Thanks in advance and moderators please feel free to move this to the keris forum if you feel that would be more appropriate, I took a shot here because of the hulu meu apet style hilt
