A blade 24 with a sharp edge 26 is fixed with the housing such that the blade extends through one of the longitudinal ends, and the blade is fixed with the housing in such a manner that it is non-movable relative to the housing. A blade protector 28 is partially disposed in the open interior of the housing and is movable in the longitudinal direction relative to the housing between a retracted position and a covering position. In the retracted position, the sharp edge of the blade outside of the housing is exposed for cutting, and in the covering position, the sharp edge of the blade outside of the housing is covered by the blade protector.</p> |
