I kēia manawa ua kūʻai aku nā mea hana he nui i nā huahana paʻa palupalu. Akā ʻo ke ala pololei e hoʻohui ai i ka lou me ka bondown palupalu he maʻi poʻo paha ia no nā mea hana. E kamaʻilio e pili ana ia ma lalo.
Nānā mua ʻia ka paona palupalu inā ʻike ʻia kahi palapala hōʻoia e like ai. Ua nānā pono ʻia kēlā me kēia kāʻei huki ma mua o ka haʻalele ʻana i ka halehanahana a loaʻa iā ia kahi palapala hōʻoia e pili ana
Pono ke kaulahao e laumania a pālahalaha, a ʻaʻole ʻae ʻia nā kīnā e like me nā māwae, nā kihi ʻoi loa, overburning, a pēlā aku.
ʻO Shackle kahi ʻano o ka maʻa, kahi e hoʻohana ākea ʻia i nā ʻoihana like ʻole e like me ka mana uila, metallurgy, ʻaila ʻaukā, mīkini, alahao, ʻoihana kemika, awa, hoʻouku, kūkulu a pēlā aku.
Ma mua o ka hoʻohana ʻana i ka shackle, e nānā pono i kona hiki ke lawe ʻia, inā he kino a hewa paha ka helehelena, a inā pili pono paha ka ʻaoʻao pili e pale ai i nā pilikia.
