I-Screwddriver-iphawu lokungafuneki kwaso nasiphi na isixhobo esibekiweyo. Kodwa oku kwiminyaka yoo-1930, yayingazange ithathelwe kwangoko luluntu lwetekhnoloji.
Inkangeleko yokuqala ye-crborsrivers ye-crowdrives ene-quale "yeflethi" ibuyela kwinkulungwane ye-XIV, iphantse yaguqukayo yayingekabikho ngaphambi kokuqala kwenkulungwane yama-20.
Ngeli xesha, izikati ezinesiliphu sele zibangele izikhalazo ezininzi, kodwa zazingaphandle kukhuphiswano ngenxa yezityholo zabo. Izinto ezingalunganga ze "classic" zibizwa ngokukodwa ngendibano enkulu, ngakumbi, kumzi-mveliso wemoto. Okokuqala, ukugqabhuka kwakungagxili, ngenxa yale nto, umatshini wescrewdrivers uhlala usonjiwe, ukushiya ukukrwada kumalungu omzimba anemikhono. Okwesibini, xa ujijekile, izikrike kunye nezikrelemnqa zihlala "zitsaliwe", zijika intloko okanye zonakalise izinto ezonakalisayo. Kulusikelwe umda kwaye baqokelele ukoyisa uluhlu lwaseMelika uJohn Thompson, ngo-1933 wayenelungelo lokuloba i-screwdriver kunye nentloko ethembekileyo. Nangona kunjalo, inzame yokuthengisa ukutshitshiswa kubavelisi bezixhobo ze-haredwanga ayizange ifumane impumelelo ngempumelelo. Ngo-1934, uThompson waqhelana nonjineli uHenry Phillips waza wachaza umxholo wokufumana kwakhe. Phillips ndiyithandile lo mbono, wathenga amalungelo elungelo elilodwa lomenzi wechiza le-thompson kwaye walungelelanisa inkampani yePhillips Screw Inkampani (isekhona). Ngo-1936, uphuhlise itekhnoloji yemveliso yezikrelemnqa. Izikrikhi ze-cradud ngokuzenzekelayo zigxile kwi-screwdriver, kwaye ayivumeli "ukutsala" - ukubethwa kwesixhobo sityibilika.
Nangona kunjalo, iPhillips yazivalela yonke indawo. Ekugqibeleni, wakwazi ukwenza umdla uYujina Calk, uMongameli waseMelika weNkampani, oyena mntu umenzi wezixhobo zekhompyutha kwi-United States. Nangona iinjineli zeNkampani zithiyile i-CLART ingabamba umbono wokuba usoyikisa "ukubandulula wonke umntu owathi akunakwenzeka ukuba uphumeze." Isisongelo sasinesenzo, kwaye inkampani, ityale imali kwimveliso yesiqingatha sesigidi seedola, yaqala ukuveliswa kwezikrelemnqa phantsi " Ngo-1937, i-GM yaqala ukusebenzisa ezi krafu kwimveliso yeemodeli zecadillac. Iziphumo zazingaqhelekanga kangangokuba ngo-1940, zonke ii-Aguricaly Autouthers zatshintshelwa ekusebenziseni i-crousaden, kwaye abavelisi be-Hardware bakhiwe ekuthengweni kwelayisensi. Ngexesha leMfazwe Yehlabathi II, abavelisi bezixhobo zomkhosi - iitanki kunye nenqwelomoya batshintshelwa kusetyenziso lwezi sikrelem.
Ukususela ngoko, izikrelem ezininzi ezahlukeneyo zazenziwa- nangaphantsi kwe-polyhedra, kwaye phantsi kwentsholongwane yeemilo ezahlukeneyo. Kodwa ngaphandle kwezinto, iikrikhi ezinqamlezayo kunye nezikrelem (ezibizwa ngokuba yiMithombo ye-English Extled (Phillips) isahlala isebenza, kwaye umnqamlezo wescrewdright sisiseko saso nasiphi na isixhobo.
