He aha nā ʻāpana o ka ʻili?

Hiki ke ʻano liʻiliʻi ke ʻano o ka bit ma muli o ka hana i manaʻo ʻia ai, akā naʻe, ʻo ka hapa nui o lākou he mau ʻano kumu like:
ʻO ke poʻo kui a i ʻole "hopena hopena"
	ʻO ke poʻo (i kapa ʻia i kekahi manawa ʻo "thump end") ka ʻaoʻao kiʻekiʻe loa o ka chisel a ua hahau ʻia me ka hāmare e hiki ai ke ʻoki ʻia i loko o ka mea.
Kino iki
	ʻO ke kino ka ʻāpana o ka bit a ka mea hoʻohana e paʻa i ka wā e hoʻohana ai.
ʻO ke kihi forging chisel
	Ma muli o ka ʻoki ʻoki a hoʻohana ʻia no ka wehe ʻana i nā ʻōpala i ʻole paʻa ka ʻoki ʻoki o ka bit.
ʻoki ʻoki ʻoki
	ʻO ka hope o ka bit e kū pono ana i ke poʻo he ʻoki ʻoki, ʻo ia ka ʻoi ʻoi i hoʻohana ʻia e ʻoki i nā mea. ʻO kekahi mau ʻano ʻoki (e like me nā wili a me nā ʻoki kālā) ʻoi aku ka nui o nā kihi ʻokiʻoki.
	He aha ka ʻoki ʻoki? ʻO ka ʻoki ʻoki e pili ana i ka ʻokiʻoki i hoʻokala ʻia. ʻO ka ʻoki ʻoki ma nā ʻaoʻao ʻelua a maʻamau he 60 degere ʻoki kihi. No ka mea aia kēia kihi ma waena o nā ʻaoʻao ʻelua o ka bit e hui pū ana ma kekahi kihi (i ʻike ʻia ʻo "apex"), ua ʻike ʻia ʻo ia ʻo "included angle".
	Hiki i nā metala palupalu ke pōmaikaʻi mai kahi kihi liʻiliʻi (e like me 50 degere) e maʻalahi iā lākou ke ʻoki ...
	… ʻoiai ʻoi aku ka hilinaʻi o kahi kihi ʻoi aku ka nui (e laʻa.
	ʻO ke kihi i makemake ʻia e pili ana i ka mea i ʻoki ʻia a ʻokoʻa paha ma muli o ka mea hana.
