A strip-cut shredder is pretty self-explaining; it cuts paper into strips. The advantage is that the paper is shredded quickly, but the degree of confidentiality of the shredded pieces is rather low. There is a possibility for the strips to be put back together, so don't shred anything too important here. For top-secret papers, use a cross-cut shredder that cuts the paper to smaller pieces where the level of security is higher.
