Fiskars Easy Change Ergo Control Rotary Cutter features a unique design that makes it easier than ever to change the blade without sacrificing cutting performance. A magnet built into the blade housing lets you remove the dull blade and quickly add a fresh blade. This also simplifies assembly so you don’t have to remember the order of washers and nuts. Other innovations include a slim design that offers right- and left-handed users a clear line of sight, a premium steel blade with titanium coating for lasting sharpness, a blade guard that retracts when you squeeze the trigger, a thumb lock to lock the blade open for continuous use or closed for safety and a longer, more comfortable ergonomic Softgrip handle to help reduce hand fatigue.
