Ua ntej lub sharpener yog invented, xaum yog sharpened nrog ib tug riam. Qhov kev tsim kho tshiab tau ua kom yooj yim rau txoj haujlwm no. Nrog nws cov tsos, cov txheej txheem tau dhau los ua kev nyab xeeb thiab yooj yim dua.
Variations ntawm ib lub ntsiab
Sharpeners tuaj hauv txhua hom duab thiab xim. Dab tsi manufacturers thiab designers tsuas yog tsis siv los kos xim rau lawv cov khoom. Tab sis lawv lub ntsiab sib txawv yog hom mechanism. Niaj hnub no muaj peb txoj kev xaiv: yooj yim los yog phau ntawv (qhov tseem ceeb ntawm kev lag luam ntawv sau), tshuab thiab hluav taws xob sharpener.
Cov cwj mem hluav taws xob tau ua rau lub neej hauv chaw ua haujlwm, qee lub tsev thiab tsev kawm ntawv yooj yim dua thaum nws los rau cov xaum ntse. Kev ua haujlwm tuaj yeem ua tiav hauv lub sijhawm luv luv. Lawv ua haujlwm los ntawm lub network, roj teeb thiab txawm tias dhau ntawm USB chaw nres nkoj. Lawv qhov txiaj ntsig tsis txaus ntseeg yog qhov muaj peev xwm ua kom cov cwj mem ntawm yuav luag txhua txoj kab.
Lub cev yog ua los ntawm cov khoom siv tiv thaiv, cov hniav yog ua los ntawm cov hlau zoo tshaj plaws. Hluav taws xob xaum sharpener muaj "pib pib" xaiv,"auto-stop", nrog rau qhov taw qhia sharpening. Niaj hnub no, Panasonic cov khoom yog nrov tshaj plaws. Lawv tau dim kev siv hauv chaw ua haujlwm thiab tsev kawm ntawv. Hluav taws xob xaum sharpeners ua haujlwm thiab ua tau raws li qhov tsim nyog zoo nkauj ntawm cov tsev niaj hnub. Cov qauv tshiab no tau nruab nrog lub kiv cua kom txias lub tshuab thiab lub tshuab txiav muaj zog heev rau kev nrawm nrawm, hloov tsis siv neeg rau kev nyab xeeb kev nyab xeeb, 6 qhov sib txawv me me rau cov xaum sib txawv ntawm cov kab sib txawv, nqus khob taw rau kev ruaj ntseg siab tshaj plaws ntawm lub cuab yeej. table.
Los ntawm keeb kwm…
Thawj tus cwj mem ntse yog patented los ntawm Fabkis tus lej lej Bernard Lassimon xyoo 1828 (Fabkis patent No. 2444). Nws tsis yog txog xyoo 1917 uas cov cwj mem hluav taws xob tau tshwm sim thawj zaug hauv chaw ua haujlwm. Tus kws sau ntawv Asmeskas David Reese txawm sau phau ntawv "Proust from the sharpener", nws lub ntsiab lus nyob rau hauv lub laj thawj ntawm yuav ua li cas ua lag luam tawm ntawm cov xaum ntse. Ib tshooj nyob rau hauv phau ntawv yog mob siab rau rau phab ntsa-mounted hluav taws xob sharpeners. Nws hloov tawm tias muaj cov neeg zoo li no hauv cov chav kawm Asmeskas.
Xaiv tus ntse
Handmade tsim yog zoo meej rau menyuam yaus. Nws muaj kev nyab xeeb, feem ntau muaj lub teeb ci me nyuam tsim. Rau qhov chaw ua hauj lwm, tau kawg, hluav taws xob xaum sharpeners yog nyiam.
Thaum yuav, nco ntsoov xyuas cov hniav. Nws yuav tsum tau ruaj thiab zoo, cov khoom siv zoo tshaj plaws yog high-carbon steel. Cov hniav tsis zoo yog luv luv. Lub xub ntiag ntawm lub thawv tshwj xeeb rau chips -yam tseem ceeb. Qhov tsis muaj lub thawv pov tseg ua rau qee qhov tsis yooj yim thaum siv. Nrog hluav taws xob sharpeners, koj yuav tsum tau them sai sai rau qhov muaj peev xwm ntawm overheating thiab suab nrov thaum ua haujlwm. Qee cov qauv ua rau lub suab nrov tsis zoo, uas yog qhov tsis txaus ntseeg hauv chaw ua haujlwm. Cia siab tsuas yog cov tuam ntxhab zoo tshaj plaws. Thiab ces tus sharpener yuav tsis yog ib tug trinket ntawm lub desktop, tab sis ib tug zoo pab.
