is there supposed to be dry humor in this thread that i'm not aware of...???
pangtuli is a knife used for circumsission. it's a rite of passage to manhood. the bayabas leaves (guava fruit tree) is chewed and spat on the newly cut foreskin and then the boys would run down the river bank and jump into the water to wash off the blood...my dad and my cousins went through this ritual at prepubescent age...i remember my uncles always trying to scare me with such a tool.
i guess it can be used as a weapon.
btw, "supot" is someone with an uncut foreskin...meaning a wrap or a pouch/bag.
