My son just bought me one of these cutters for Mother's Day. It's on the way. Woo hoo! Do you have to use the Martelli blades or will any 45mm blade replacement work? I'm a big blade changer. If it's not slicing through four layers effortlessly, I toss it.
My arm is so messed up from cutting. My wrist gets it at times too. Icky bubbles of fluid. I'm hoping this cutter will give me some relief. New blades have to be cheaper than a new arm. The doc just says to stop cutting. Like that's going to happen.
