ʻO ka mīkini hoʻoheheʻe ʻana i ke one he mea hana maʻamau, kahi i hoʻohana nui ʻia no ka ʻoki ʻana i nā ʻano ores a me nā pōhaku, me ka granite.ʻO ka Granite he pōhaku paʻakikī e koi pinepine i ka ikaika paʻi kiʻekiʻe e wāwahi iā ia i loko o ka nui o nā mea i makemake ʻia.
Hoʻopiʻi ka mīkini hana one counterroll i nā mea ma o ʻelua mau wili liʻiliʻi a hana i kekahi mea i hoʻopau ʻia.Ma muli o kona ʻano maʻalahi a me ka hana maʻalahi, hiki iā ia ke hoʻomaikaʻi i ka hana hana i kekahi ʻano.Eia nō naʻe, hoʻopili ʻia ka hoʻopuka ʻana o ka mīkini hana one roller e nā kumu he nui, e like me ke ʻano mea, paʻakikī, haʻahaʻa a pēlā aku.No kekahi mau mea me ka paʻakikī liʻiliʻi a me ka haʻahaʻa haʻahaʻa, ʻoi aku ka kiʻekiʻe o ka hana ʻana o ke one o ka mīkini hana one roller.
