Twenty seven years ago, I bought my first rotary cutter from Fiskars. Last year it suddenly refused to stay open while cutting, so I figured it was time for a new one. I bought another Fiskars. I figure if the first one lasted so long, buy the same again. The only difference in the two is the original had a gray handle and the new one has an almond colored handle. I originally bought the first one, (an ergonomic) because I was teaching my "lefty" DD to sew, and the Fiskars was easy to switch from left hand to right hand. Care fully remove the blade, flip the handle and reassemble it. Easy Peasy.
