Brilliant idea!
I have a version this on my pet's nail clippers that are made with them. The pet type is more like scissors, one side has a little plate you can swing around behind the opening so that you don't have to worry clipping the dark colored nails short when the quick is hidden. Really surprised there aren't any for people, especially for baby and elderly folks.
Thanks. I've never had the urge so bad to click no on the "Is this info helpful" question before.
