By far the most common method of disposing of your sensitive documents is shredding.
Since we’re mostly addressing home shredding, we’ll be discussing the most common commercially available shredders and what their capabilities are.
Before we get into the types of shredders, let’s go over the current security levels for
Security Level 1 (for shredding general internal documents): Strip-Cut – 3/8” or Cross-Cut – between 3/8” x 1-1/2” and 3/8” x 3-1/8”

Security Level 6 (for shredding of top secret documents – NSA/CSS approved): Cross-Cut 1mm x 5mm (approx. 1/26″ x 1/5″)
Most office supply stores don’t list shredders by their respective security levels, but most list the dimensions of the cut in the product details.
Commercially available, Strip-Cut, Cross-Cut and Micro-Cut. Strip-Cut and Cross-Cut are the way to go in terms of the security.
