What is a Gobang?

[KuKulzA28]

My Indonesian Hokkien friend told me recently that a Gobang is a large version of a parang, so perhaps a tinggi one, and that often they are left dirty and rusty. Part of the reason for that is said to be so that infections and tetanus will result if there is a fight and the enemy escapes wounded.

Anyone know anything about Gobangs?

Is that just a local colloquial term for large machete-types or are there specific examples of gobangs?


Thanks.
