Toki kakau rakau mō te mahi rakau, te tapahi rakau

E rua ngā āhuatanga o te mahi whakairo rakau mā te whakamahi i te toki: ko te tuatahi, kia kaua e whara te tinana o te tangata, kia tiakina ai te haumaru o te tangata; ko te tuarua, kia kaua e tapahia te raina waituhi ki te whakamahi i te toki hei tapahi rakau, he whakangaro i te rakau, he moumou taima, he kino hoki te rakau.

Ko ngā pūkenga o te tapahi ki te toki kāore e whara i te tinana, ko te nuinga kei roto i te whakaaro tika mō te whakamahi i te toki, te hopu tika i te kaha, te tirohanga tika ki te tapahi rakau, te ringa matau, te whakamahinga pai o te ringaringa, me te whakahaere tika i te hinengaro. E rua ngā tikanga tapahi o te mahi whakairo whakapaipai ki te ringa kotahi, me ngā ringa e rua ki te toki. Tū kotahi te ringa o te toki, piko te waewae ki mua, piko tetahi ki muri, neke atu i te whānui o ngā waewae i te whānui o ngā pakihiwi. I te wā e tapahi ana, whakatakotoria te rakau ki mua, me te ringa kotahi e pupuri ana i te rakau, me te ringa tetahi e pupuri ana i te mua o te kakau o te toki. Me pā paku te pito o muri o te kakau o te toki ki waho o te waewae o muri. Ina tapahia te toki, me mirimiri te pito o te kakau rakau ki te waewae o muri, mehemea he kaha rawa te kaha tapahi, he koretake rānei te tapahi, me hoki te mata o te toki ki muri i muri i te hurihanga me te whara o te tinana.

Hei tāpiritanga, nā te toki ka mirimirihia ngā taha o muri o te tarau ki runga, ki raro hoki, ka taea te hopu pai i te kaha tapahi o te werohanga, ka taea te whakahaere i te ringaringa o te kaitākaro i te wā kotahi, kaua e kaha rawa te hopu, kaua e whara, nā te mea rānei he tuwhera rawa te tawhiti o ngā waewae o muri, ka uaua rawa te ringa kotahi ki te toki, kaua e tohe kia roa rawa, ka pā ki te tere tapahi.
