Vim yog qhov kev xaiv ntawm cov hmoov hlau thiab pob zeb diamond, qhov ntse thiab lub neej ntawm cov saw hniav yog kev tsis ncaj ncees. Ob qho tib si ntse thiab ruaj khov saws tsis muaj dab tsi, feem ntau tus nqi kim dhau, cov tuam txhab tsim khoom lag luam tsis tuaj yeem txais.
Sharp saw hniav feem ntau xaiv cov hlau mos hmoov hmoov tom qab alloying, lub pob zeb diamond tau nthuav tawm sai sai thaum txiav, lub pob zeb diamond sib tsoo cov khoom siv ceev ceev, thiab qhov ntse yog qhov zoo. Nyob rau tib lub sijhawm, cov hniav profile ntawm lub cuab yeej lub taub hau kuj pab kev sib tsoo ceev nrog tib daim ntawv qhia. Lub taub hau tsim tau zoo ua rau kev khiav tawm ntawm nti sai dua thiab ntau qhov chaw txiav, ua rau cov npoo ntse dua.
