The Grip series of Faber-Castell like, the good experience with the high-quality, ergonomically shaped paint and pencils have led to the choice of the appropriate doses Spitzer - although it is not practical just for's pencil case, since, with a height of about 6 5 cm and width of about 4.3 cm applying simply too thick. The decisive reasons for buying the rather expensive bipartite Spitzer were also that it is designed for the current narrow and wide color / pencils contains (for the pins diameter 8 mm and 11 mm) and container for the sharpening waste. Experience with three grip sharpeners are rather poor: 1. In two out of three sharpeners the upper separated after a short time from the bottom - without plucking or tearing, alone's Open. 2. Then versackten with two individually incorporated sharpener in the housing by normal pressure, which, after all, only the appearance, but not the functionality did demolition. 3. is more severe: All sharpeners wear already occurred after only a few months: they pluck and tear the pins, also breaking times at the top of pieces from mines. Besides himself leiert the case: If you want to open a container to empty, goes quite happy times of the other, and crumbles the desk. In short, the grip Dosenspitzer is not mature. Instead of sensitive folding solution an ordinary screw would be better. The durability of the existing majority of plastic Spitzer leaves to be desired. My 10 years old metal sharpener supplies still prima Spitz results, the Grip contributed just a few months good services.
