Nā tōna hoahoa koi, piko hoki ka taea te tapahi ngāwari ki te oneone kiato, ka whakarato i ngā kaha pakaru oneone. Ka whakaitihia e tēnei te ātete ki te kukume tarakihana, ā, ka whakapai ake i te whai huatanga o te whakahoki whenua, ka waiho hei whiringa pai mō ngā mahi whenua maroke me ngā mahi mara raihi.

Ko te mata parau whenua he wāhanga matua hei āwhina i ngā mīhini ahuwhenua pērā i ngā tarakihana. Ko te nuinga o te wā ka whakamahia i roto i ngā mahi mara mō te parau whenua, te tango i ngā tarutaru, te tango i ngā otaota, me te kuru i ngā kakau witi. Hei wāhanga pakaru, ka wetekina te oneone, ka whakapai ake i te whakakīkī o te oneone, ā, ka tapahia, ka tanumia hoki ngā taru me ngā kakau witi ki roto i te oneone mā te parau hurihuri, mā te wawahi rānei i te oneone, ka hangaia he āhua pai mō te moenga purapura mō te whakatipu i muri mai. Ko tēnei hua he mea hanga ki te maitai kaha-teitei hei tu atu i te pānga taumaha me te pakaru i roto i ngā taiao oneone uaua.

Hei whakarite i te pakari i raro i ngā āhuatanga mahi uaua, ka whakamahia e te mata whakaora te maitai puna koranu kounga teitei (pēnei i te 60Si2Mn, 60Si2MnA, 28MnSiB, me te 65Mn) hei rauemi turanga. Ka whakamahia te hangarau hanga tika i te wā hanga, me te maimoatanga wera martensitic, hei whakahaere tika i te pakeke o te hua i roto i te awhe HRC 42-48 (ka whakamahia e ētahi kaihanga te HRC45±3). Ka hua ake tēnei i ngā āhuatanga miihini whānui tino pai, e whakakotahi ana i te pakeke teitei me te pakari pai, e ārai ana i te pakaru me te kakahu wawe.
