3 different lines, transparent baffle varnish Adjustable brass sharpener from DUX At the beginning of the 50´s, DUX developed a sharpener which makes it possible to set the sharpness of the pencil point in three variations. The
impetus arose out of enquieries from users in different disciplines who wanted to have the leads of their pencils at different sharpnesses. A technical
draughtsman or an architect, for example, likes a very sharp point, while a designer or an artist prefers a rather blunt pencil for his sketches.
The variable sharpener developed by DUX takes account of these different applications. A knurl attached to the end of the sharpener makes it
possible to adjust it for three different pencil points. The knurl can be heard and felt clicking into place when it is turned. Depending on the setting,
the pencil is allowed to enter more or less deeply into the interior of the sharpener. The precisely set angle between the cone and the blade ten
produces the desired point.
