Izindwani zokusika amaphepha embonini yokucubungula amaphepha zibukhali futhi zihlala isikhathi eside, futhi izindwani zingakhiqizwa ngokuya ngezidingo zabasebenzisi. Impahla yalolu hlobo lwama-blades ngokuyinhloko yinsimbi enesivinini esikhulu, futhi kunezinhlobo ezimbili zama-blades ensimbi anesivinini esikhulu kanye nensimbi enesivinini esiphezulu efakiwe. Ibukhali futhi izinzile, ikhwalithi yokusika inembile futhi ibushelelezi, ilungele zonke izinhlobo zephepha, ikakhulukazi ukusika amaphepha ahlukahlukene anegremu eliphezulu, ama-blades akhetha amamaki ahlukene ensimbi enesivinini esikhulu (W3, W4, 6542, W18Cr4V, M2, M35, M42, SKH-9, SKH-51) ngokwezindlela ezahlukene zokusika kanye nemikhiqizo yokusika ukukhiqiza, ubulukhuni bungafinyelela ku-67 HRC. Ukwengeza, kweminye imikhiqizo ekhethekile, siphinde senze ama-tungsten carbide blades ahlanganisiwe noma ama-tungsten carbide blades. Le nqubo yenza impilo yethuluzi ihlale isikhathi eside, futhi impilo yomkhiqizo we-tungsten carbide blades izoba izikhathi eziningana ngaphezulu ngaphansi kwenqubo evamile.
