Imithetho yeThupha xa ukhetha isarha yetafile, isarha yesarha okanye isarha esetyhula:

• Amagqabi anamazinyo amaninzi anika ukusika okugudileyo.Amagqabi anamazinyo ambalwa asusa imathiriyeli ngokukhawuleza, kodwa athanda ukuvelisa ukusika okurhabaxa kunye ne "tearout" eninzi. Amazinyo amaninzi kuthetha ukuba kuya kufuneka usebenzise izinga lokutya elicothayo

• Kungakhathaliseki ukuba luhlobo luni lwesarha oyisebenzisayo, uya kuthi ekugqibeleni ugqibezele nentsalela kwincakuba yesarha.Kuya kufuneka ucoce le ntsalela usebenzisa isinyibilikisi sepitch. Ngaphandle koko, i-saw blade yakho iya kubandezeleka "kwi-blade drag" kwaye inokuvelisa amanqaku okutshisa emthini.

• Musa ukusebenzisa i-rip blade ukusika i-plywood, i-melamine okanye i-MDF.Oku kuya kukhokelela kumgangatho osezantsi wokusika kunye ne "tearout" egqithisileyo. Sebenzisa iblade enqamlezileyo okanye, nokuba ngcono, i-triple-chip blade yomgangatho olungileyo. 

• Ungaze usebenzise iblade yokukrazula kwisarha yesarhanjengoko oku kunokuba yingozi kwaye kuya kubonelela ngokusikeka komgangatho ophantsi kakhulu. Sebenzisa i-blade enqamlezayo.

• Ukuba uceba ukusika umthamo omkhulu wezinto ezithile, kunokuba kuhle ukuthenga i-bladeeyenzelwe ngokukodwa loo nkcazelo.Uninzi lwabavelisi banikezela ngolwazi lweblade yesikhokelo somsebenzisi. Ngokwemvelo, bonke abavelisi beeblade bacinga ukuba iiblade zabo zezona zilungileyo, ngoko ke unokubhekisa kulwazi olungentla ukukunceda ngakumbi.

• Ukuba awufuni ukutshintsha iiblade rhoqo kwaye uhlala usike izinto ezahlukeneyo, njengoko kunjalo ngabantu abaninzi, kunokuba ngcononamathela nge umgangatho olungileyo indibanisela blade.Umyinge wamazinyo ngama-40, ama-60, nama-80 amazinyo. Okukhona amazinyo ethe chatha, kokukhona acocayo ukusikwa, kodwa kokukhona licotha izinga lokutya.
