It is very comfortable to hold and the prongs are claw shaped non rigid and definitely non scratch.
This is a fun little idea to try if you like to try new things and don’t like to pet a cat with your hand for some reason. This comb is very soft, light, and flexible, and is more like fingers running through your hair than a real detangling comb. For that reason, it really should be seen as a novelty cat-scritching item to spoil your cat with than a grooming tool. For a sensitive cat with a very thin coat that barely sheds, this would work fine, but for such a cat, simply scratching them with your hands or giving them a bristle brush shine would achieve the same result.
