How the Pencil Sharpener Was Invented

For years , the knife was the most unremarkably used creature to focalise the wooden writing instrument known as a pencil ( which historian think was invented in the fifteenth or sixteenth century ) . But whittle the wood away to eventually bring forth a degree was a fourth dimension - consuming , tedious , and inexact process . As pencils became more omnipresent in mundane sprightliness , it became ostensible that a faster and more efficient elbow room was demand to sharpen them . fortunately , two Frenchmen were up to the challenge .

On October 20 , 1828 , Parisian mathematician Bernard Lassimone applied for and was issued French patent identification number 2444 for his invention of the “ taille wax crayon , ” translate to English as “ pencil sharpener . ” A twelvemonth after receiving a letters patent , the “ taille crayon ” was promote in the Le Constitutionnel , an influential political and literary newspaper out of Paris , as the preferable way to sharpen pencils . It employed two small metallic element files tilted at ninety degrees in a block of Sir Henry Wood that mold to whittle , scrape , and grind the wood off the pencil to create a peak . Though this was the first mechanically skillful pencil sharpener , it was n’t much quicker , nor less piece of work , than just using a knife .

About ten years later , in 1837 , the British pick up on this sharpening furor . Cooper and Eckstein ’s “ patent pencil arrow ” debut in The Mechanic ’s Weekly , a scientific weekly found and edited by Joseph Clinton Robertson . They named their invention the “ Styloxynon ” and it was jolly secretive to Lassimone ’s sharpener in its description , “ two sharp single file neatly and unwaveringly set together in right angles in a humble cylinder block of rosewood . ” It was actually given the branded content treatment in The Mechanic ’s Weekly with the writer ( who presumably was Robertson , see he wrote most of the content in the cartridge holder ) saying , “ From capital personal widget , I have myself experienced in the exercise of the ingenious little musical instrument … I feel insure that I shall be rendering an of import service to all such of your numerous readers as are draughtsmen , by infix it to their notice through the medium of your page . ”

Needless to say , a good pencil sharpener than the Styloxynon was still needed .

A decade after the Styloxynon , another Frenchman , Therry des Estwaux , design something we still apply today in pencil sharpeners . Estwaux invented a conical - shaped equipment that , when a pencil was inserted and twisted , all side of the pencil were whittled away at once , make the sharpen cognitive process much ready . Today , it is known as a prism sharpener . From that point on , sharpener using a conical - shape machine began protrude up throughout Europe , though with slight design change from Estwaux ’ sharpener . They were also used in offices across the domain . In fact , theEarly Office Museumtracked down support that showed the New York City municipal government buy mechanical pencil sharpener for their offices as betimes as the winter of 1853 from an English company for one buck and fifty per sharpener ( about $ 42 today ) . As the requirement for pencil sharpener grew , so did the demand to mass produce them to get the Mary Leontyne Price down .

Enter Walter K. Foster , who , according to many sources , patented the first American pencil sharpener in 1851 , utter with an advance on the original conical design , so that it could be more well mass produced . However , upon further research , we could find no patent under Walter Foster until 1855 , which is really under “ Waltee K. Fostee ” ( though that is a literal ) . The patent , US 12722 , is for “ Improvement in molds for casting pencil - sharpener , ” and it describes how to in good order create molds so as to mass produce the gimmick .

By 1857 , a written report in a trade journal state that Foster and his employees were churn out over 50 gross ( 7,200 ) of the sharpener per sidereal day due to the “ the demand for exportation to Europe increase every day . ” By 1860 , The Practical Draughtsman ’s Book of Industrial Design out of France was include that now “ the Americans supply us with something simpler and cheaper . ”

For the next thirty age , the pencil sharpener would be mass - produce across the world in various different sizes , shapes , and mode of whittling and scraping off wood . Yet , the pencil sharpener still was n’t perfect – with the major problem being that all of them command the user to either deform the pencil and take for the sharpener steady or twist the sharpener and keep back the pencil steady to get the desire sharp peak . The 1896 A.B. Dick Planetary Pencil Pointer exchange all of that .

Designed sort of like a monorail paper tender , the user inserted a pencil into a “ chow ” – a mounted wood holder – as two milling disks “ revolved around their axis vertebra as they orbited the wind of the pencil . ” After a few moments , one had a perfectly sharpened pencil . In 1904 , the Olcott Pencil Sharpener utilized a cylindric cutting head for clean undercut .

Around the same time as the A.B. Dick Planetary Pencil Pointer , a man in Falls River , Massachusetts noticed a dissimilar need in coitus to the pencil sharpener . John Lee Love was a carpenter by trade wind , so he always had a penury for a pencil . He needed a sharpener that was portable , well-heeled - to - usage , and would n’t make a spate . So , he designed and patent his own .

UnderUS patent of invention # 594114 , simply titled “ pencil sharpener , ” the patent describe a simple , light - system of weights , chalk - powered pencil sharpener that caught the shavings . Plus , as it is write in the patent , it could also act as as a “ as a paper - free weight , desk ornament , and for other and standardized purposes . ” This sharpener was eventually ring the “ Love Sharpener . ”

The next authoritative founding for the pencil sharpener was adding electrical energy . While it seems electric pencil sharpener were in reality invented around 1910 , they were n’t commercially get until 1917 by a troupe called Farnham Printing & Stationery Co out of Minneapolis . Even then , while galvanising pencil sharpener were around and used by large offices , this type of sharpener did n’t become widely useable to the world until the 1940s . And the rest , as they say , is account .
