He papa whakairi me ngā kōhao pūtu kei muri hei hono mau ki te pakitara parau me te pakitara parau, kia māmā ai te huihui me te wetewete. Kua tāpirihia e ētahi tauira he rara whakapakari ki muri, kia pai ai mō ngā oneone kohatu, oneone uku taumaha rānei.
Te ātete ki te kakahu: Ka taea e te roanga mahi o te mata te eke ki te 300-500 mu/wahi (i runga i te momo oneone), neke atu i te 50% te roa atu i ngā parau maitai waro noa.
Āhuatanga whakakoi-ā-ia anō: Ka whakamahia e te mata mahi he hoahoa pakeke rerekē, ka pupuri aunoa i te koi o te mata i te wā e whakatipu ana, ka kore e hiahiatia te whakakoi pinepine.
