ʻO nā mīkini i ka hana ʻana o ka pahu metala huinaha me ke kihi shear, kūpono, pololei, wikiwiki, ʻano huahana hydraulic, pneumatic a me pedal, lāʻau lapaʻau, lako kila, lako keʻena metala, nā mea kuke, nā lako a me nā ʻoihana ʻē aʻe he mea pili loa ia.

Hoʻohana nui ʻia kēia lako no ka ʻoki ʻana i nā mea metala a me nā mea ʻaʻole metala. Hoʻohana i ke kaomi hydraulic e like me ka mana, ka neʻe mālie, ka ikaika, e hiki ai ke hana ʻia ka mānoanoa o ka mea. ʻO nā mea pahi me ke kila metala kiʻekiʻe. (Cr12MoV), ka paʻakikī quenching o HRC 58/62, ka hoʻopau ʻana i ka ʻili, e hōʻoiaʻiʻo ana i ke ola o ka mea hana a me ka maikaʻi o ka hana ʻana. Loaʻa i kēia mīkini ka wikiwiki o ke kaʻina hana, ke kūlana kiʻekiʻe, ka mana hilinaʻi, ka hana maʻalahi, ka hoʻoponopono ʻana, ka mālama maʻalahi, ka lōʻihi o ke ola lawelawe, a pēlā aku. ʻO nā lako makemake ʻia no nā ʻoihana hana pepa metala.
