My old Fiskars sewing scissors have seen better days so when I saw the Razor at a great price on Overstock, I jumped at the chance to update. These scissors are the bomb. As an earlier reviewer said, they cut " though 6 layers like butter." I wasted about 30 minutes one day folding scraps into various thickness just to see where I would reach some resistance. 10 layers of mid-weight cotton upholstery material didn't faze them. I gave it up at that point. I love these scissors!
