Mata Tāra Hurihuri, Mata Ngaki Piko, Mata Tāra 2-pōha, Mata Parau Ahuwhenua
1. Te Whakarite Whenua: He taputapu hurihuri hei whakaoti i te huri me te kuru oneone.
pakaruhia ngā paparanga oneone kiato, ka waihanga i tētahi taiao oneone ngāwari mō te rui i ngā hua whenua pērā i te witi,
kānga me te raihi;
2. Te Horoi i te Papatūānuku: Kuruhia te kakau witi, ka whakahokia mai i muri i te hauhake hei tango i ngā toenga o te mara, me
whakaiti i te ātete mahi mō ngā kotinga o muri mai;
3. Mahi maha-āhuatanga: He pai mō te whakangāwari i te oneone, te tango otaota me te whakatipu i ngā pae i roto i ngā māra hua rākau
me ngā māra huawhenua, tae atu ki te parau me te whakapūpū i te māra raihi hei whakapai ake i te whai huatanga o te parau i te oneone.
Kakau o te Mata: E rua ngā kōhao whakatika tika hei hono haumaru ki ngā mīhini ahuwhenua, kia mau tonu ai te pumau, ā, kāore e nekeneke i raro i ngā kawenga taumaha.
Pane Mata: Ka whakamahia he tukanga piko āhua-pewa, tae atu ki ngā mata tapahi-mua me ngā mata tapahi-taha. Ko tōna piko ahurei (tata ki te 119°-120°) me te tautuhinga teitei ka whakaiti i te ātete i te tapahi ki te oneone, ka hua ake he pakaru oneone pai ake, he hohonu mahi ōrite hoki.
Hei whakatutuki i ngā hiahia mō te ātete kaha ki te pānga me te ātete ki te kakahu, he mea hanga te tinana o te mata mai i ngā rauemi maitai puna pakari-teitei pērā i te 60Si2Mn, 60Si2MnA, me te 28MnSiB.
I muri i te maimoatanga wera pakari (te whakawhiti āhua martensitic), ka whakahaerehia te pakeketanga whānui o te hua i waenga i te HRC 42 me te 48, kia kore ai te mata e whati ngāwari, e pōuri rānei i raro i te pānga kaha. Hei tāpiri, ko ētahi tauira he paninga koranu rewa-wera i runga i te mata o te mata, e kore e whakarei ake i te ātete kakahu engari he mahi "whakakoi-ake" anō hoki—arā, ka pupuri i te koi o te mata o te mata i te wā e kakahuria ana, ka whakaiti i te whakapaunga hiko me te whakatutuki i te penapena pūngao.
He whānui te hototahi o tēnei hua ki ngā tarakihana nunui me ngā tarakihana rahi-waenga, ā, he tino pai mō te whakaora whenua, te tapahi tarutaru tawhito, me te keri i ngā papa whenua mania, whenua maroke, me ngā pari ngawari. Ka taea e ia te wawahi i ngā paparanga oneone kua kikī, te whakanui ake i te pūngao o te oneone, me te whakarato i te taiao whakatō purapura kia mahorahora, kia manawa hoki mō te whakato hua i muri mai.
