Reusable knife (R)evolution - The knife with the 2nd life
This patented circular knife has been specially developed for companies that use circular knives with different diameters. The objective was to produce the knife in a resource-saving manner and to save material costs. This way, e.g. the energy-consuming heat treatment needs to be executed only once for the full life-time of the knife. Furthermore, it is fully recyclable.
The illustration shows the two cutting edges of the circular knife, connected by a predetermined breaking point in between. This knife has a diameter of 150mm, if the upper cutting edge is broken off, the diameter is reduced to 130mm. Up to now, circular knives that have reached a certain number of regrinding stages have been sorted out and disposed of.
To prevent the knife from being simply disposed, DIENES inserts a "breaking point" during production. Once the 150mm knife has reached its final sharpening stage, the first cutting edge is cut off and the 130mm knife is sharpened. The customer then has a 130mm knife, which is used like a new knife in the next machine.
