A paper shredder that meets the DIN P-5 safety level is intended to irreversibly destroy personal data, for example by government and defense authorities. The DIN class of a shredder indicates how well the paper is destroyed. The higher the number after the 'P', the more strips or shreds your shredder creates. DIN P-5 paper shredders turn an A4 into about 1000 so-called microchips, after which documents can't be restored. A P-5 shredder is also called a micro-cut shredder.
