First pair unusually ground and not sharp. But the company sent me a new pair for free and told me to keep what I have but when the new pair came here. Well, as you can see from the photo, I squeeze as hard as they let me (the handles touch) and they don't even cut a 1/16 inch popsicle. You can see how many times I've tried. I knew I should have just cracked up and spent $50 to cut the nipples that Amazon sells.
