This comes up every once in a while.

Hand claws in DR are punching weapons like this: https://dviw3bl0enbyw.cloudfront.net/uploads/forum_attachment/file/33176/pantera.jpg

Hand claws in DR are not additions of claws like this: https://img1.etsystatic.com/055/0/5985802/il_fullxfull.688609877_nz59.jpg

I.e. A CLAW attack with the former would still only engage your normal fingers.

That said, the latter is known as a claw gauntlet, which could be something to suggest as an addition to DR. It could either be an armor template, a weapon template, or simply a special weapon available during a paid event like the blowguns.
