If you're an entrepreneur, then you would also be in a fragile situation if you do not shred your papers in the right demeanour. Take care and make sure you don't get a strip cut shredder - cross cut shredders break the papers into a large number of pieces and you finish up truly shredding the paper irreversibly.
These are high-powered shredders that will shred not only papers, but complete books, CDs, info disks and even pieces of metals. These are sufficiently good to shred almost all of the papers, and papers in serious quantities. Ensure that for real security you get a cross cut shredder and not a strip cut one, and gt one that comes out of a good brand to avoid frequent system jams. This is counseled for extremely sensitive documents.
