Dab tsi ntawm cov hniav los yog anvils muaj rau loppers?

ncaj hniav
	Cov hniav ncaj yog cov hniav zoo nkauj tshaj plaws ntawm loppers thiab qee zaum hu ua "txiab" vim nws zoo ib yam li cov hniav.
	Cov hniav lopper ncaj yuav tsis tshua kim dua li lwm cov qauv, tab sis tsis muaj cov txiaj ntsig ntawm cov hniav nkhaus thiab tuaj yeem yooj yim xaub tawm cov ceg thiab stems thaum siv.
Curved Hniav
	Feem ntau hom hniav siv nyob rau hauv niaj hnub lopper designs yog nkhaus, nrog rau cov nkhaus ntawm lub sharpened sab saum toj hniav txuam nrog uas tsis yog-pointed hauv qab hniav.
	Xwb, ib lub lopper tuaj yeem muaj qhov nkhaus, tsis txhuam hniav thiab ncaj, ntse hniav.
	Curved hniav muaj peb lub ntsiab zoo:
	Lub curvature ntawm ib tug unsharpened hniav, ib feem encircling ib ceg los yog pob tw los ntawm hauv qab no, pab tiv thaiv nws los ntawm slipping ntawm lub puab tsaig.
	Thaum lub siab yog thov, qhov khoov ntawm cov hniav tsis sib txuas, ua ke nrog lub zog siv los ntawm cov hniav ntse, thawb cov ceg ntoo thiab stems rov qab mus rau fulcrum (qhov taw tes sab hauv ntawm lub puab tsaig), ua kom lub zog siv zog.
	Thaum ib tug sharpened hniav yog nkhaus, nws tsub kom lub zog ntawm lub point ntawm kev sib cuag, muab ib tug me me cheeb tsam ntawm kev sib cuag ntawm lub ntse ntug thiab ceg los yog lub cev. Qhov me me ntawm qhov chaw sib cuag ntawm cov hniav nrog cov ceg, lub zog ntau dua yog concentrated nyob rau hauv ib qho chaw thiab qhov huv ntawm qhov txiav.
ncaj anvil
	Ib yam li cov hniav ncaj, cov pob txha ncaj ntawm lub lopper yog daim ntawv tseem ceeb tshaj plaws thiab pheej yig, tab sis nws tsis muaj txiaj ntsig ntawm qhov nkhaus, hooked, lossis serrated anvil.
	Nws yog qhov yooj yim dua rau cov ceg ntoo thiab cov stems kom plam tawm ntawm lub qhov ncaj ncaj, ua rau kev khiav ntev dua thiab kev txiav tawm ntau dua li tuaj yeem ua tiav nrog cov qauv tsim niaj hnub.
Curved Anvil
	Lub nkhaus anvil ua haujlwm ntawm tib lub hauv paus ntsiab lus raws li cov hniav nkhaus, ib feem ntawm cov ceg, thiab yuav tsum tau siv nrog cov hniav nkhaus sab saum toj.
	Lub curvature ntawm anvil tiv thaiv ceg thiab stems los ntawm slipping tawm ntawm lub lopper puab tsaig thiab pab kom cov ceg thiab stems ze rau lub fulcrum. Ib yam li cov hniav nkhaus, lub pob zeb nkhaus kuj tseem hu ua "hooked anvil" vim nws muaj peev xwm tuav ib ceg lossis qia thiab tiv thaiv nws los ntawm zawv zawg dawb.
notched anvil
	Ib tug serrated los yog "toothed" anvil muaj ib tug series ntawm notches (los yog cov hniav) raws nws nto.
	Los ntawm kev muab kev sib txhuam ntawm cov ceg thiab qhov chaw ntawm lub qhov quav, qhov no tso cai rau cov ceg ntoo thiab cov stems yuav tsum tau nyem txawm tias nruj dua, ua rau nws yuav luag tsis yooj yim rau lawv plam los yog xoob thaum txiav.
	Cov pob zeb tsis zoo yog qhov zoo rau siv rau hauv qhov chaw ntub dej lossis qhov chaw ntub dej uas cov tawv ntoo tuaj yeem nplua thiab ua rau nws nyuaj rau tuav cov ceg thiab stems.
