The Roll@Blade trimmer, pronounced roll "a" blade, is a professional paper trimmer that has been carefully designed to handle the daily trimming needs of an office or workshop. You can buy the Akiles Roll@Blade rotary trimmer online in two sizes: either 18" or 36". The blades are made of durable tungsten steel and are self sharpening, lending to a longer life. The dual cutter rails offer a very smooth and stable motion that lends to an accurate trim. The Roll@Blade has a see-through clamping bar to hold pages in place while not obstructing your view of the cutting line. Metric and English grid ruler markings make getting a perfectly straight line in the perfect location very easy. In addition to paper, the Roll@Blade precision trimmer by Akiles is strong enough to trim newsprint, thin cardboard, laminate films, vellum, aluminum foil, thin vinyl and poly, leather, and many more materials up to 2mm thick.
