He parau rua-upoko (tau wāhanga: 1733321 / 73332)
E piri ana tēnei raupapa o ngā pito o te parau ki te ariā hoahoa wehewehe tawhito. Ki te whakatauritea ki ngā parau kotahi-wahi tuku iho, ko te tinana pito o te parau anake me whakakapi i muri i te pakaru, me te kore e whakakapi i te turanga parau katoa, ka tino whakaiti i ngā utu tiaki. Ko te tinana matua o te hua he mea hanga ki te maitai koranu kounga teitei (pēnei i te 65Mn, 60Si2Mn rānei) mā te hangarau hanga wera matatau, ka hua ake he hanganga ā-roto matotoru, kāore he kōhao onepu me ngā pūwero, ā, he tino ātete ki te pānga me te pakari.
Mata Whakairo: Mā te tukanga tinei motuhake ka eke te pakeke o te mata ki te Rockwell HRC 45-57, he tino teitei te ātete ki te kakahu, ā, he ngāwari ki te tu atu ki te pakū kino o te oneone onepu, o te whenua kirikiri rānei.
Tūranga whakairi: Ka pupuri i te pakari me te ngāwari taketake o te rauemi, ka ārai i te pakarukaru ina pāngia ngā pūtu whakairi e te ahotea, ina pāngia rānei e ngā mea mārō i te parae, kia mau ai te haumaru mahi.
Roanga Roa: Mā te hoahoa pane-rua ka taea te tango i te pito parau, te huri i te 180°, me te tāuta i tētahi mata tapahi hou ki tērā taha i muri i te tawhito o tētahi mata. Mā tēnei āhuatanga "kotahi te mata, e rua ngā whakamahinga" ka roa ake te roa o te oranga o tētahi hua, ka penapena i te 50% o te auau whakakapinga me te haumi pūtea a ngā kaiwhakamahi.
Pānga Whakakoi-ā-Whaiaro: Mā te āhuahanga kua arotauhia ka mau tonu te koi o te pito parau i a ia e neke ana i roto i te oneone, ka whakaiti i te kukume o te tarakihana, ā, ka whakaiti i te whakapaunga wahie.
Hototahi whānui: Ka hototahi tēnei tauira ki ngā momo waitohu parau papa pokepoke me ngā parau oneone o raro, ā, he mea tino pai mō te parau ahuwhenua hou, te keri i ngā papa whenua, me ngā mahi keri awaawa.
