This cutter allows easy sampling of paper and film specimens for tensile and folding endurance. The blade is made of a material strictly selected and processed with meticulous tempering and refined. All these ensure safe use for a long time with sharp cutting performance. A stopper precisely parallel to the counter-blade makes accurate specimens. A cum system interlocks a stopper precisely mounted on the counter-blade with a cutting blade. A specimen-holder that automatically moves downward and upward perfectly secures the specimen. So, it is not necessary to hold the specimen with the left hand, ensuring safe and easy operation.
