What is the particle size and how does this relate the security level?
Swordfish shredders shred each sheet of paper into tiny pieces of paper. The particle size is simply the size of one of these pieces of paper and the smaller the paper particle size, the higher the security. Swordfish Level 3 Security Cross Cut shredders will shred an A4 sheet into 400-500 pieces where as Level 4 Security Micro Cut shredders will shred an A4 sheet into more than 2,500 pieces.
