practicality of a bladed gauntlet a la the wolverine's claws? perhaps with less thin blades.
The only real problem with wolverine’s claws is figuring out where he stores them when they’re not in use. They’re supposed to sit in his forearm, which causes all kinds of logistical weirdnesses for how the blades are supposed to pass through his wrists. X-23 has the same problem, for what it’s worth.
There are several different unarmed claw weapons. Off hand, the Bagh Nakh comes to mind. This is a set of (usually) five small, curved blades, mounted on a strip (I’ve seen metal and leather, I think wooden braces also exist), or on the inside of an open handed gauntlet, that slip between the fingers, and allow the wielder to strike with an open hand and then rake the victim with the blades by pulling their fingers back.
There’s also a variant where the blades mount facing out from the palm, and can serve as a combination weapon and climbing tool, though I honestly, do not remember the details there.
The only real problem with Wolverine’s claws is the logistics of actually integrating blades like that into a (pseudo) human body. Attaching them to a wrist gauntlet is a legitimate option.
That said, it’s worth remembering, this is basically like giving a character an over-engineered knife. It’s good for dealing with unarmed opponents, but when facing a foe using anything approaching an actual weapon, like a fire axe, sledgehammer, or crowbar, they’d be at a disadvantage again.
So, yes, they’re practical in the narrow range of situations they’re designed for, and not so much the rest of the time.
