If indeed Lapu-Lapu had used kampilan to kill Magellan, IMHO it doent deserve much recognition either because of the number of Spanish soldiers were too small comparatively, and were fighting in an unfamiliar territory for the first time
I think the later part of battles in the southern Philippines against the Moros whom were synonimous to kris (sundang in Malay) and barong deserved more attention - thus the much credit to the kris.
