Isaha yebhetri yisarha ephathwayo, esebenza ngoomatshini esika ngamazinyo adityaniswe kwitsheyini ejikelezayo ehamba ecaleni kwebha yesikhokelo.Isetyenziswa kwimisebenzi efana nokugawulwa kwemithi , ukugawula iinyawo , ukubethelwa kwemithi , ukuthena , ukusika izinto zokunqanda umlilo endle kunye nokuvuna iinkuni .I-Chainsaws ene-bar eyilwe ngokukodwa kunye neendibaniselwano zekhonkco ziye zaphuhliswa njengezixhobo zokusetyenziswa kwi-chainsaw art kunye ne-chainsaw mills.Ii-chainsaws ezikhethekileyo zisetyenziselwa ukusika ikhonkrithi.Ngamanye amaxesha i-chainsaws isetyenziselwa ukusika umkhenkce, umzekelo we-ice sculpture kunye naseFinland ukuqubha ebusika.Umntu osebenzisa isarha ngumsarha .
Ilungelo elilodwa lomenzi wechiza lokuqala le “sarha yekhonkco engapheliyo” (isarha equka ikhonkco lekhonkco elithwele amazinyo esarha nokubaleka kwisakhelo sesikhokelo) yanikwa uSamuel J. Bens waseSan Francisco nge-17 kaJanuwari 1905. Injongo yakhe yayikukuwa. iinkuni ezinkulu ezibomvu.I-chainsaw yokuqala ephathwayo yaphuhliswa kwaye yanikwa ilungelo elilodwa lomenzi ngo-1918 ngumbhali wokugaya waseCanada uJames Shand.Emva kokuba evumele amalungelo akhe ukuba aphelelwe ngowe-1930 uyilo lwakhe lwaphuhliswa ngakumbi yinkampani yaseJamani iFesto ngowe-1933. Le nkampani ngoku isebenza njengeFestool ivelisa izixhobo zombane eziphathwayo.Abanye abaxhasi ababalulekileyo kwi-chainsaw yanamhlanje nguJoseph Buford Cox kunye no-Andreas Stihl;le yamva inelungelo elilodwa lomenzi wechiza kwaye iphuhlise i-chainsaw yombane ukuze isetyenziswe kwiziza ze-bucking ngo-1926 kunye ne-chainsaw esebenza ngepetroli ngo-1929, kwaye yaseka inkampani ukuba ivelise ngobuninzi.Ngowe-1927, uEmil Lerp, umseki weDolmar, wavelisa isarha yokuqala yehlabathi esebenza ngepetroli waza wayivelisa ngobuninzi bazo.
IMfazwe Yehlabathi II yaphazamisa ukunikezelwa kweesarha zaseJamani kuMntla Melika, ngoko ke abavelisi abatsha bavela kuquka i-Industrial Engineering Ltd (IEL) ngo-1947, umanduleli wePioneer Saws.Ltd kunye nenxalenye ye-Outboard Marine Corporation, umenzi omdala we-chainsaws eMntla Melika.
UMcCulloch eNyakatho Melika waqala ukuvelisa i-chainsaws ngo-1948. Iimodeli zakuqala zazinzima, izixhobo zabantu ababini kunye nemivalo emide.Ngokufuthi iisarha zamatsheyina zazinzima kangangokuba zazinamavili afana neesarha zokutsala.
Emva kweMfazwe Yehlabathi II, ukuphuculwa koyilo lwealuminiyam kunye noyilo lwenjini kwenza ukuba iisarha zibe khaphukhaphu kangangokuba umntu omnye wayenokuzithwala.Kwezinye iindawo abasebenzi betyibilizi (i-chainsaw) bathatyathelw' indawo yi-feller buncher kunye ne-harveer.
Iisarha ezityatyekwayo zithathe indawo yeesarha ezisetyenziswa ngabantu kumahlathi.Ziza ngobukhulu obuninzi, ukusuka kwiisarha ezincinci zombane ezenzelwe ukusetyenziswa ekhaya nasegadini, ukuya kwiisarha ezinkulu "zokugawula imithi".Amalungu eeyunithi zobunjineli bomkhosi aqeqeshelwa ukusebenzisa isarha njengoko benjalo abacimi-mlilo ukulwa nomlilo wamahlathi nokuphefumla imililo yezakhiwo.
