I-chainsaw yebhethri iyisaha ephathekayo, eyimishini esika ngesethi yamazinyo exhunywe ochungechungeni oluzungezayo oluhamba eduze kwebha yomhlahlandlela.Isetshenziswa emisebenzini efana nokugawula izihlahla , ukusika izithombo , ukuthena , ukuthena , ukusika izicishamlilo ezindaweni zokucisha umlilo kanye nokuthenwa kwezinkuni .Ama-chainsaw ane-bar eklanywe ngokukhethekile nezinhlanganisela zamaketango athuthukisiwe njengamathuluzi okusetshenziswa kubuciko be-chainsaw kanye nezigayo ze-chainsaw.Ama-chainsaws akhethekile asetshenziselwa ukusika ukhonkolo.Ngezinye izikhathi ama-chainsaws asetshenziselwa ukusika iqhwa, isibonelo ukwenza izithombe zeqhwa naseFinland ukubhukuda ebusika.Umuntu osebenzisa isaha uyisaha .
Ilungelo lobunikazi lakuqala le“saha elingapheli” elisebenzayo (isaha elihlanganisa uxhaxha lwezixhumanisi ezithwala amazinyo esaha futhi ligijima ohlakeni oluqondisayo) lanikezwa uSamuel J. Bens waseSan Francisco ngoJanuwari 17, 1905. Inhloso yakhe kwakuwukuwa ukuwa. redwoods ezinkulu.I-chainsaw yokuqala ephathwayo yathuthukiswa futhi yanikezwa ilungelo lobunikazi ngo-1918 ngu-Millwright waseCanada u-James Shand.Ngemva kokuba evumele amalungelo akhe ukuba aphele ngo-1930 ukusungula kwakhe kwathuthukiswa nakakhulu yilokho okwaba yinkampani yaseJalimane i-Festo ngo-1933. Le nkampani manje isebenza njenge-Festool ikhiqiza amathuluzi kagesi aphathwayo.Abanye ababambe iqhaza ababalulekile ku-chainsaw yesimanje nguJoseph Buford Cox no-Andreas Stihl;laba banelungelo lobunikazi futhi benza i-chainsaw kagesi ezosetshenziswa ezindaweni zokubhakha ngo-1926 kanye nesaha elisebenza ngophethiloli ngo-1929, futhi basungula inkampani ezozikhiqiza ngobuningi.Ngo-1927, u-Emil Lerp, umsunguli we-Dolmar, wasungula i-chainsaw yokuqala yomhlaba esebenzisa uphethiloli futhi wakhiqiza ngobuningi.
IMpi Yezwe II yaphazamisa ukuhlinzekwa kwamasaha aseJalimane eNyakatho Melika, ngakho kwavela abakhiqizi abasha kuhlanganise ne-Industrial Engineering Ltd (IEL) ngo-1947, eyandulela i-Pioneer Saws.Ltd kanye nengxenye ye-Outboard Marine Corporation, umkhiqizi omdala wama-chainsaw eNyakatho Melika.
UMcCulloch eNyakatho Melika waqala ukukhiqiza ama-chainsaws ngo-1948. Amamodeli okuqala ayesinda, amadivaysi abantu ababili anemigoqo emide.Ngokuvamile amasaha ayesinda kangangokuthi ayenamasondo afana namasaha okudonsa .Ezinye izingubo zazisebenzisa imigqa eshayelwa kusukela kuyunithi yamandla enamasondo ukushayela ibha yokusika.
Ngemva kweMpi Yezwe II, ukuthuthukiswa komklamo we-aluminium nokwakhiwa kwenjini kwenza amasaha alula kangangokuthi umuntu oyedwa wayengawathwala.Kwezinye izindawo izisebenzi zokushibilika (ama-chainsaw) zithathelwe indawo yi-feller buncher kanye nokuvuna .
Ama-chainsaws acishe athatha indawo yamasaha asetshenziswa abantu emahlathini.Zingamasayizi amaningi, kusukela kumasaha amancane kagesi ahloselwe ukusetshenziswa ekhaya nasengadini, kuya kumasaha amakhulu “agawula imithi”.Amalungu amayunithi onjiniyela bezempi aqeqeshelwe ukusebenzisa amasaha njengoba kunjalo nezicisha-mlilo ukulwa nokusha kwehlathi nokuvuthisa imililo yezakhiwo.
