Ngā wāhanga mīhini ahuwhenua 65Mn maitai tineia te koko parau ātete-kakahu
Ko te koko parau, e mōhiotia whānuitia ana ko te pito parau, ko te pito koko rānei, te wāhanga tino nui, tino tere hoki te pakaru o te oneone i roto i ngā mahi parau. Hei paionia o te parau katoa, ka tapahia tika ki roto i te oneone, ā, ko ia te kawenga mō te tapahi i te oneone me te whakaiti i te ātete. Ehara i te mea ka whakarite noa ngā parau me ngā koko kounga teitei i te hohonutanga o te parau, engari ka whakaitihia hoki te kawenga tōia o te tarakihana, ā, ka whakapai ake i te penapena wahie.
Ko te raupapa parau me te koko he mea whakamahi noa i te maitai boron kounga teitei (pērā i te 30MnB5, i te rauemi rite rānei) hei papa. Whai muri i te tukanga whakamahana motuhake, ka taea e te pakeke o te pito koko te eke ki te HRC 48-52, ā, ka mau tonu te pakari o te kakau koko me te wāhi whakapuru. Mā tēnei āhuatanga "pakari ki waho, pakari ki roto" ka taea ai e ia te ātete pai ki te pakaru me te pakaru i te wā e anga atu ana ki te whenua onepu me te toka, ā, ka ārai i te pakaru, te piko rānei.
He koko parau whānui: he pai mō te whakatipu oneone noa me te oneone onepu.
Paru whakawhanui/whakawhānui: i hangaia mō te oneone taumaha, mō ngā mahi parau hōhonu rānei, hei whakanui ake i te koki tomo kia pai ake ai te pakaru o te oneone.
He koko parau momo whakaora: he mata koko matotoru, he pai mō te whakaora i te whenua ururua he nui te kirikiri.
Hoahoa mata koi-ake: Ahakoa te pakaru me te haehae o te parau, ka noho koi tonu te pito o te koko, kia pumau ai te ōwehenga parau me te whakaiti i te whakapaunga wahie.
Te maimoatanga mata: Tāpirihia he paninga ārai waikura katoa hei ārai i te waikura i te wā e penapena ana, e kawe ana hoki.
