Siziingcali ekuveliseni iiblade zesinyithi ezisetyenziswa kakhulu ekuqhekezeni ngokuchanekileyo izinto ezifana nentsimbi engagqwaliyo, ifoyile yekopolo, kunye nefoyile ye-aluminium. Zenziwe nge-carbide, zilungiswe ngobushushu nge-vacuum, kwaye zigaywe ngocoselelo, zifikelela kukumelana okuhle kokuguguleka kunye nokumelana nokuqhekeka. Zinikezela ngokusika okugudileyo, okungenamigxobhozo, kunye nokunciphisa uxinzelelo, okwenza zifaneleke kwizicelo ezikhawulezayo nezinoxinzelelo oluphezulu. Zibonelela ngozinzo olukhethekileyo ekuqhekezeni amaphepha amancinci kunye nokusika rhoqo kweentsimbi ezithambileyo, zandisa ubomi bezixhobo ngokufanelekileyo, ziphucula imveliso, kwaye zinciphisa iindleko zokusebenza zizonke.
