Inganda za sima, zishingiye cyane kumukino wumupira kugirango wo gusya ibikoresho byafashwe neza bikenewe muguhindura sima. Ni nako bimeze no gukora ibicuruzwa byangiza nibikoresho bishya byubaka. Ibikoresho byongeraho, bikoreshwa mugukora ubushyuhe {{2} ibicuruzwa birwanya nka ceramic hamwe namatafari yumuriro, amatafari yumuriro, kandi wishingikirije kumupira wamaguru kubyo baremye.
Ariko ntabwo ari ibikoresho byo kubaka byungukirwa no gukoresha urusyo. Bakoreshwa kandi mugukora ifumbire, gufasha gukora intungamubiri -} itezeza imbere guteza imbere ibihingwa bizima. Mubyongeyeho, urusyo rwabacuruzi rukoreshwa mwirabura kandi ntabwo -}}} Icyuma cyicyuma, gufasha gukuramo amabuye y'agaciro y'ibikoresho.
Urusbo rwabacuruzi rwakomeje kwerekana ko ari igikoresho kidasanzwe kandi cyingirakamaro mu nganda zitandukanye. Ubushobozi bwayo bwo gusya mu ifu nziza yabigize igikoresho cyingenzi cyo gukora ibicuruzwa byinshi. Munganda zicukura amabuye y'agaciro, urusyo rwabacuruzi rwashoboje gukuramo amabuye y'agaciro ava mu mabuye y'agaciro, kongera imikorere mu bucukuzi bw'amabuye y'agaciro.
Muri make, umupira wumupira nipimbo ryinshi ryimashini zifata inganda zitandukanye. Guhinduranya nubushobozi bwo gusya ibikoresho byombi byumye kandi bitose bigira umutungo wingenzi kugirango ubone umusaruro utabarika. Hamwe nubushobozi bwayo bwo kubyara ifu yubunini butandukanye, bifasha gukora byinshi mubicuruzwa twishingikiriza buri munsi.
