He mea hono ki te pou tango hiko o te tarakihana, ka huri tere ki te tapahi i te oneone, ka tutuki ai ngā mahi whakauru o te pakaru oneone, te tango kakau witi, me te whakataurite whenua. Hei wāhanga āwhina e whakamahia nuitia ana i roto i ngā mīhini whakarite whenua, ko tōna kounga te mea e whakatau tika ana i te whai huatanga me te utu o ngā mahi ahuwhenua.

Ko tēnei raupapa o ngā wīra hurihuri e whakamahi ana i te maitai koranu kaha-teitei (pērā i te 60Si2Mn) hei rauemi turanga, ā, he mea hanga mā te hanga mate hei whakarite kia nui te mātotoru o te mata, ā, kāore he kino huna. Hei aro ki ngā āhuatanga o te pakū o te oneone, ka whakamahia e mātou he tukanga maimoatanga wera matatau: i muri i te tineitanga o te kaukau tote katoa, ka whakamahanahia i tētahi pāmahana motuhake, ka tutuki ai te pakeketanga o te mata o te 55-60 HRC, ko te kakau e mau tonu ana te pakari o te 45 HRC, e hanga ana i tētahi hanganga pakeke-rua "pakeke ki waho, pakari ki roto" he ātete ki te kakahu me te pakaru.

Hangarau paninga ātete-kakahu: Hei aro ki te pakaru tere o ngā oneone onepu, kei te wātea he paparanga ātete-kakahu kua whakarewahia ki te plasma. Ka honoa he paninga koranu matotoru 1.5-2mm ki te mata tapahi, ka tutuki te pakeketanga o te 58-65 HRC, ka roa ake te ora ratonga mā te 3-5 ngā wā ki te whakataurite ki ngā mata maitai 65Mn noa.

Hoahoa ārai-raruraru: Ko te koki piko o te mata me te pewa āhua-marama kua whakapaitia, me te wāhanga whakawhiti maeneene, ka whakatau pai i te raruraru o te raruraru o te kakau witi i roto i ngā mara raihi, i ngā wāhi rānei he maha ngā puranga kakau witi, ka whakaiti i te kawenga tarakihana.
