Incredible as it may seem, the OLFA® TS-1 lets you cut the top sheet only, without damaging the ones below.

You can adjust the blade depth very precisely so it works with a variety of materials including newspaper, card, vinyl and tape.  When cut object is as thin as a piece of newspaper, move the slider towards "MIN", and to the contrary, when the cut object is thicker, slide it towards the "MAX".

Auto-pressure control system adjusts cutting pressure

The TSB-1 blade is exceptionally long-lasting, and two spare blades can be held in the body of the cutter itself.
