Paperknife
Metal, wooden, bone, ivory or plastic knife (approx. 20-25 cm long),
usually in one piece, with a flat and narrow (approx. 0.5-1 cm) blade that
tapers towards the end. The edge is not sharp and the point is relatively
blunt. With a paperknife you can easily cut open envelopes and books; it is
inserted respectively into the fold of the cover or between two uncut
leaves of a book and then cut open along the fold. Sometimes the letter
opener is equipped with a pocket knife at the other end. Another paperknife
model has a razor-sharp blade (approx. 3 cm) in a rectangular plastic
handle, which is no thicker than 4 mm. This type of paperknife is not to be
confused with the folder. [MOT]
