With aluminum foil everything works fine. But then the shock - no matter how often I drive the upper knife on the plastic wrap or not, whether I push or pull, whether with slightly strained foil or loose fit - take a cut always only a thin knife track.
Again a Monday device? Inevitably come up to the old prejudices "professional" -Bodenwischer Leifheit who suffers in several details of quality and design defects.
As the comparison of the two knife does not continue due to different cutting geometry, only the analysis of the strange oscillating knife brings the solution. False clipped! It is true when a small triangular tip cutting moves over the film. Swings the knife against it with the long legs between stops, it is incorrectly assembled. Instead, both long leg rest against the attacks of the housing.
The glossy plastic wrap is hard to envisage the shiny white cut trough and grasp, offers further potential for improvement.
Love Leifheit managers, instead gripe a hot tip from many years of experience with safety-related components in metal and plastic: Quality comes almost automatically when Poka Yoke and the tolerances of components and processes fit together. The latter will cost in the development process may a lot of time and money, but it pays off. Really!
