Ke kaʻina hana hana paipu kila humuhumu ʻole. Wahi a ke kaʻina hana hana, ua māhele ʻia nā paipu kila humuhumu ʻole i nā paipu kila humuhumu wela, nā paipu kila humuhumu anu, nā paipu kila humuhumu i hoʻopaʻa ʻia a kīkoʻo ʻia, a me nā paipu kila humuhumu i hoʻopuka ʻia ma ke ʻano kū pololei. Hoʻohana ʻia nā kaʻina hana mua ʻelua e hana i nā paipu kila humuhumu caliber maʻamau, ʻo ke anawaena o ia mea he 8-406, a ʻo ka mānoanoa o ka paia he 2-25; hoʻohana ʻia nā kaʻina hana hope ʻelua e hana i nā paipu kila humuhumu paia mānoanoa nui, ʻo ke anawaena o ia mea he 406-1800, a ʻo ka mānoanoa o ka paia he 20mm-220mm. Wahi a ke hoʻohana ʻana, hiki ke māhele ʻia i lokonā paipu kila humuhumu no nā hale, nā paipu kila humuhumu no nā wai, nā paipu kila humuhumu no nā paila, a menā paipu kila humuhumu no nā paipu aila.
