Winkelmesser kann, allseits, innen und außen zum Zeichnen sowohl mit Eusehe als aueh mit Blei Verwendung finden. Ba die Zeiehenkanten nur etwa 1 mm betragen, ist die gefahr des Terkantens des Bleistiftes vermindert. 2rotz der Zeichenkanten besitzt der Winkelmesser die gleiche Festigkeit wie ein solcher von rechteckigem Querschnitt von 2 bis 2,5 mm Stärke· Beim Zeichnen entlang seinen Kanten wirft der Winkelmesser praktiseh keinen Schatten. Ir ist auch in seiner Gestaltung sehr formschön.Protractor can be used on all sides, inside and outside for drawing find use with both Euseheeh and lead. Ba the Toe edges are only about 1 mm, there is a risk of edging of the pencil diminished. Despite the edges of the characters, the protractor has the same strength as a protractor with a rectangular cross-section from 2 to 2.5 mm thick When drawing along its edges, the protractor throws practically no shadow. Ir is also in its design very shapely.
