I've no idea about the 'Keris Anak Alang' contest. Would appreciate if you could shed some light into this event, though.
In Singapore, this will be the first keris competition (i think). Therefore, the organising committee will be doing it on a trial and error basis. Future competition will be fine-tuned based on the feedback received.
(I'm not in the committee, i'm just an enthusiatic supporter).
If it received overwhelming response, it may be extended into a regional competition and even global competition. (Err... I think not on the global scale yet, however). One day perhaps...
