Lub handsaw feem ntau muaj ob qhov chaw: saw saw thiab saw hniav.
Pom Frame:
Muaj nuj nqi: Lub saw thav duab yog siv los tuav thiab zawm cov saw hniav, muab kev ruaj ntseg thiab lub zog xa mus thaum sawing.
Hom: Pom thav duab feem ntau muab faib ua cov khoom ruaj khov thiab kho tau. Tsau saw thav ntawv muaj ib qho yooj yim tsim, tab sis tuaj yeem tuav ib hom saw hniav nkaus xwb, txwv lawv qhov yooj. Adjustable saw thav duab tau muab faib rau hauv pem hauv ntej thiab nram qab seem; sab pem hauv ntej tuaj yeem txuas ntxiv thiab thim rov qab hauv seem tom qab, yog li ua kom pom cov hniav sib txawv ntawm qhov ntev, ua kom yooj yim ntawm kev siv thiab ntau yam. Tam sim no, adjustable saw thav ntawv tau dav siv vim lawv qhov yooj yim.
Saw Hniav:
Muaj nuj nqi: Lub saw hniav yog qhov tseem ceeb ntawm lub tes xuas tes txiav; nws cov hniav ntse zoo txiav cov ntaub ntawv xws li ntoo thiab hlau.
Nta: Cov khoom siv thiab cov hniav tsim ntawm cov hniav txiav txiav nws cov kev ua haujlwm thiab ua haujlwm ntev.
