This is a Pedang Spunjer .
The forms are numerous .
Sumatran perhaps .
I've got one of these clad in thin low grade silver ; the blade's a little different (thick and wedge shaped) ; shorter at 17" . The tip curves down to meet the upcurving edge . My example has a much more pamor like blade with no fuller and is shaving sharp .
A slight draw and snap of the wrist and it'll pickle chip a pool noodle effortlessly .
