Yes, Justin brings up an excellent point (again like the one on my head
). There are some spears from Borneo that also do not have pamor, or at least not noticable pamor. In fact, some Borneo tombak may be Moro or linked to Moro spears since there are Moros living on and around Borneo. This may explain the square peksi (though I have seen mostly round Moro peksi).
