Amabuye y’ibirahuri akenshi afise ubukomezi buri hagati ya 6 na 7, mu gihe amabuye y’ivyuma afise ubukomezi buri hagati ya 7,5 na 8,5. Ivyo bipimo bishingiye ku rugero rw’uburemere bwa Mohs, rupima ubushobozi ikintu gishobora guhangana n’ugukororwa canke gukororwa. Amabuye y’ivyuma, kubera ko arimwo ibintu vyinshi vy’ivyuma, arafise ubukomezi bwinshi, ivyo na vyo bikaba bisobanura ko ashobora guhangana n’ugusambuka- kandi ashobora kuguma afise ingaruka zo gukata uko igihe kigenda kirarenga.
1. Ubukomezi bw'amabuye y'ibirahuri
Amabuye y’ibirahuri, nk’ikintu gikomeye gisanzwe, akoreshwa cane mu gusukura ibikoresho nk’ivyuma, amapulasitike n’ibiti. Ubusanzwe, ubukomezi bwavyo burava kuri 6 gushika kuri 7, ivyo bikaba vyerekana ubushobozi bwavyo bwo kunanira gukororwa canke gutera imbere iyo bishikiwe n’inkomezi zo hanze. Naho zikomeye cane, amabuye y'ibirahuri ashobora kugira ubuzima buke mu bidukikije bimwebimwe vy'ugusaza cane.
2. Ubukomezi bw'amabuye y'agaciro
Ugereranije n’amabuye y’ibirahuri, amabuye y’ivyuma yerekana akamaro kanini mu gukomera. Amabuye y’ivyuma akoreshwa mu gukoranya ibikoresho vyinshi vy’ivyuma, ivyo bikaba bituma akomera cane kandi akaguma adashobora kwambara. Ubukomezi bwavyo busanzwe buva kuri 7,5 gushika kuri 8,5, bikaba bituma amabuye y’agaciro akora neza cane mu gukuraho utunenge two ku ruhande no kugabanya ivyonona ivyuma mu gihe c’ibikorwa nk’ugutera imiti n’ugutera umunyota. Ugukomera cane kw’ibipande vy’ivyuma vy’ivyuma bisigura kandi ko biguma bikora neza igihe kirekire, bikaba bituma bikora neza kandi bikagabanya n’ibiciro.
3. Ikoreshwa ry'amabuye y'ibirahuri n'amabuye y'agaciro y'ivyuma
Ivyo bikoresho vyompi vy’ibirahuri n’ivy’ivyuma vy’ivyuma bikoreshwa cane mu gusukura ivyuma. Amabuye y’ibirahuri akoreshwa canecane nk’ibikoresho vyo gushaza canke vyo kwuzuza, bituma ibintu bimera neza kandi bikaba bimeze neza biciye mu guterana no gutera. Ku rundi ruhande, amabuye y’agaciro yitwa alloy microbeads arakoreshwa cane mu bikorwa bisaba gusukura ahantu, nk’ugutera umunyota neza no gutera imiti, kugira ngo umuntu ashobore guheza neza cane.
