Te Wehewehe i waenga i ngā Whānau Utauta Hiko: Ngā Kani Mita, Ngā Kani Toko me ngā Kaiwhatu

Ko te mīhini tapahi kōtaha (Chop saw, Cut off saw rānei) i tapaina nā te mea he maha ngā wā e whakamahia ana hei tapahi i ngā kōtaha whakarewa, i ngā rauemi kōtaha rite rānei; ko ngā rauemi tapahi pēnei i ngā kōtaha, ngā pae, ngā paipa, te maitai koki, me ētahi atu, ko ēnei rauemi he rite tonu ngā Wāhanga whakapae. I ngā rā o mua, nā ngā take rauemi me ngā take hangarau, he uaua te whakamahi i te kaha o ngā mata kani TCT (Ungsten-Carbide Tipped) hei tapahi tonu i ngā whakarewa, inā koa ngā whakarewa rino (Ferrous metal)! Nō reira, ka whakamahia e te mīhini tapahi kōtaha tikanga ngā poro wira huri kapia. Ko ngā wāhanga matua o ngā poro wira huri he mea whakakoi pakari me ngā mea here kapia; ka whakamahia e ngā poro wira huri te huri hei tapahi i ngā rauemi whakarewa. I roto i te ariā, ka taea e rātou te tapahi i ngā rauemi tino mārō, engari he tino iti te pai o te tapahi (he puhoi), he haumaru. He ngoikore te mahi (ka pakaru te wira huri), he tino iti hoki te roa o te ora o te wira huri (he tukanga ngaronga-ā-ia-anake hoki te tapahi), ā, ka puta he nui te wera, ngā mura me ngā haunga i te hurihanga, ā, ka rewa pea te wera e puta mai ana i te tapahi, ka kino hoki te rauemi e tapahia ana, nō reira, ko te tikanga, kāore e whakamahia mō te tapahi i ngā rauemi kore-whakarewa.
