Summary[edit]
Description2 mm mechanical pencil, H Leads and sharpener.jpg |
English: This is a collection of utensils associated with the 2 mm mechanical pencil represented by yellow artefact, by Koh-I-Noor Hardtmuth, with a Faber-Castell H hardness leads container and a vintage sharpener for mechanical pencils marked "BREVETE DANS TOUS LES PAYS" and "SWISS MADE". The sharpener is used by mounting a lead in the mechanical pencil, extending it some 5 mm, inserting the tip of the pen in the hole in the top ball as far as it goes, and moving the protruding end of the pencil in a circular motion. The ball will guide the pencil and lead around the abrasive inner surface of the sharpener, and this grinds the lead into a sharp tip.
The sharpener can be divided into its parts by unscrewing the bottom. This releases the ball, and also allows the perhaps unsuspecting user to empty the grounds from sharpening. The pencil and the leads package are recent (circa 2016) acquisitions, while the sharpener stems from the early 1960s. |
