Hullo everybody!
Willem, just to remind you:
- A lot of Madurese were soldiers of the VOC/KNIL. So, not surprising if some traditional Madurese implements ended up in the Atjeh theatre.
- Thus supposing a Madura origin, your implement would be a member of the sickle ( arek/arit ) family. Try looking up info under arek/caluk/carok/clurit ( celurit )/kudi ( monteng ). Then decide for yourself what to call it.
- Looking at your blade, I would be very wary of calling it a 'tranchang' anything.
(BTW .... why didn't you get the sword as well?)
Best,
