The GreenBoard Wood Paper Trimmer from Dry Lam is a precision paper trimmer with a 12-inch cutting length and the capacity to cut up to 30 sheets of 20 lb bond paper at a time. The hardened, high carbon steel blades are self-sharpening for a lifetime of precision performance. The 3/4"-thick solid wood baseboard features a permanent 1/2" grid for precise alignment and includes imperial and metric scales. For safety, the cutting arm incorporates a patented automatic blade latch, which locks with every cutting motion, and a protective finger guard that runs the length of the cutting surface. The blade arm features an ergonomic hand grip for comfortable repeated use, and the nonskid rubber feet keep the trimmer from moving while in use.
