If you're looking for a safe and secure way in which to dispose of confidential documents or those pre-approved credit card application forms that arrive as junk mail then a cross-cut paper shredder might just be the machine for you. Consisting of two sets of blades - one set that cuts vertically and another set that cuts horizontally - cross-cut paper shredders slice paper up into small particles that resembles confetti. This makes it very difficult indeed for any fraudsters, who are looking for discarded information so that they might steal your identity, to put documents back together again.
Cross-cut paper shredders are available across a variety of DIN security settings. DIN security numbers, which were formulated in Germany - DIN standing for "Deutsche Industrie Normierung" or "German Industry Standard" in English - have been adopted globally by manufacturers and government organizations. The most basic cross-cut paper shredders are classified as Level 1, where the particle size is 3/8" x 1-1/2". Level 1 machines provide only low-level security protection as the size of the particles shredded are still quite large. Cross-cut paper shredders with a level 3 or level 4 DIN security value provide adequate protection for most personal and business uses, although cross-cut machines up to a level 6 DIN security setting do exist.
Security though comes at a price. Cross-cut paper shredders are overall more expensive than strip-cut paper shredders. They also require more in the way of maintenance and also process paper at a slower speed as they have to make twice as many cuts than do strip-cut paper shredders.
