The Logan 500 Mat Knife now features a quick adjustment blade holding knob for 8-ply. The knob allows a user to quickly loosen the blade from one depth setting and reset it to a different setting in seconds -- the blade holding knob no longer needs to be removed when resetting the blade depth.
This design improvement will not impact the everyday low price. For straight cutting matboard down to size. Use with any suitable straight edge, including Logan Adapt-A-Rule, Logan Team System, and most Logan board mounted cutters. Three depth settings: safety, single sheet, and double thick. Includes three extra blades. Uses Logan 270 blade.
