As close as us humans can get to having 3 retractable blades built into each hand
You can find these bladed knuckles for sale online. Pantera Claws or Wolverine claws are the name. The above version sells for about $30 us which leads me to believe they are meant to be a wall ornament and not a functioning weapon.
The above picture is of a UK border official showing off a confiscated pair of these bladed knuckles. Any one who has seen a good x-men comic or movie has seen wolverine wield his claws and has surely fantasized about having the same ability
Above is a simplified version of the bladed weapon
above. This claw weapon is an aluminum cast of the actual claws used in the holly wood x-men movies. The way they are designed it makes it look as if the blades are protruding from the knuckle area
The guy above is a well known wolverine wanna be who has crafted his own retracting and extending bladed claws. With the same hair do and side burns I cant help but chuckle a bit. He does resemble Hugh Jackman,below
