I’ll admit, I’ve been cutting my nails for decades, and I never once questioned that little hole. I assumed it was for hanging the clipper on a hook (which, to be fair, is one of its uses). Or maybe it was just a manufacturing quirk—a relic of how the tool was made
hen I mentioned it to a friend, and he said, “Oh, that’s for fixing bent . You put the nail of another clipper in the hole to bend the blade back.”
