Erasers - Sharpeners
2 Sharpeners
In 1821 there were already a variety appliances used for sharpening pencils. Points were
sharpened using one or more files.
Towards the end of the 18th century, similar kinds of sharpeners to the ones we know today
began to appear on the market.
2.1 Metal sharpeners and tub sharpeners
Material
We offer metal sharpeners made out of a magnesium-aluminium alloy and
polystyrene plastic sharpeners with metal blades.
Sharpeners are available in single-hole or double-hole versions, with or without tub for the
shavings.
Tub sharpeners offer the advantage that the shavings are collected during the sharpening
process. The tub can then be emptied as required.
In order to ensure an optimal sharpening of blacklead and coloured pencils it is essential to use
a high quality sharpener. Only sharpeners that have been specifically designed in line with the
characteristics of the respective types of pencil are able to offer protection against damage,
such as lead breakage.
Note on use
Writing and drawing are two different applications and, as such, have different
requirements. For writing, the tip should be pointed. For colouring, a blunt point is
more suitable. (See p. 10)
