sharp works great for ingrown toenails [SEP] these are super sharp i have used this kind of clippers for over a decade when i first opened these i felt like they were so sharp that i could do some serious damage either i am used to them now or they have dulled just a tiny bit but they are wonderful ten times better than anything i have ever bought from a store i have really bad ingrown toenails in one of my big toes but i have removed both of them with these what relief be sure to keep the little plastic tip protector that comes with it it protects the tip of the blades when they are stuck in a drawer it also prevents you from getting poked with it accidentally
