The sepokal blade of your bugis blade is designed that way. It's not an apple to apple comparison to a bahari/anak alang/alang class blade.
Bugis Sepokal blades does have an angular profile. My examples.

Hmmm... this angular profile does not qualify as a luk. On second thought, yours is an angular profile too, so NO luk for you.

Therefore Rick, yours is an Anak Alang (no luks).
