Greetings everyone:
I'm lucky to have chanced upon this piece- so far the longest twistcore Moro kris I've encountered (23in blade length, 28in overall), also the heaviest (0.75kg). It's also a nice surprise that it's not as "flexible" or thin-bladed as the other twistcore krises I've had (I could bend the other blades easily with my knee or even hands). This one is rigid, similar to the rigid blade build of late 1800s heavy battle krises. I'm guessing it's two twisted bars at the center, and two non-twisted bars at the outer (correct me if I'm wrong).
A Malay guru told me the pattern is similar to "cindai pamor" among the Malays, and "kurisi aslo" among the Bugis. I'm not familiar with keris stuff, but would be interested in what other forum members think of this assessment. I've only used vinegar to do a light etch.
TIA!
