Incredible as it may seem, the TS-1, TOP SHEET CUTTER with adjustable Auto Pressure Control function and a room for 2 spare blades, cuts only the top sheet! When cut object is as thin as a piece of newspaper, move its adjuster towards MIN sign, and to the contrary, when the cut object is thicker, slide its adjuster towards MAX sign and try. The “TS-1” takes its dedicated high quality alloy tool steel made, sharp and long-lasting blade “TSB-1” only.
