Kodi mbali za tchiseli ndi chiyani?

Maonekedwe a bitiyo amatha kusiyanasiyana pang'ono kutengera ntchito yomwe idapangidwira, komabe, ambiri aiwo ali ndi mawonekedwe ofanana:
Mutu wa chisel kapena "mapeto amphamvu"
	Mutu (omwe nthawi zina umatchedwa "thump end") ndi gawo lapamwamba kwambiri la chisel ndipo amamenyedwa ndi nyundo kuti chiselcho chidulire zinthuzo.
Thupi pang'ono
	Thupi ndi gawo la kachidutswa kakang'ono kamene wogwiritsa ntchito amagwiritsa ntchito.
Chisel forging angle
	Mphepete mwachitsulo imatsatira m'mphepete mwake ndipo imagwiritsidwa ntchito kuchotsa zinyalala kuti m'mphepete mwa pang'onopang'ono musatseke.
Chisel kudula m'mphepete
	Mapeto a pang'ono moyang'anizana ndi mutu ali ndi nsonga yodula, yomwe ndi yofiira yomwe imagwiritsidwa ntchito podula zipangizo. Mitundu ina ya tchiselo (monga zodzigudubuza ndi tchipisi ta ndalama) imatha kukhala ndi m'mphepete mwake.
	Kodi mbali yocheka ndi yotani? Kudulira kumatanthawuza mbali yomwe mbali yocheka imapangidwira. Zovala zozizira nthawi zambiri zimapindika m'mphepete mwa mbali zonse ziwiri ndipo nthawi zambiri zimakhala ndi ngodya yodulira ya madigiri 60. Chifukwa ngodya iyi ilipo pakati pa mbali ziwiri za pang'onopang'ono zomwe zimalumikizana kumapeto kwina (kotchedwa "apex"), imadziwika kuti "included angle".
	Zitsulo zofewa zimatha kupindula ndi ngodya yaying'ono (monga madigiri 50) kupangitsa kuti ikhale yosavuta kudula…
	… pamene ngodya yaikulu (mwachitsanzo madigiri 70) idzakhala yodalirika, yomwe imakhala yothandiza pazitsulo zolimba.
	Mbali yofunikira imadalira zinthu zomwe zadulidwa ndipo zingasiyane malinga ndi wopanga.
