How shall I say this politely....
The knife the Merc is holding is about as far away from reality as a knife can get. And if anyone tells me that he is wearing spiked knuckles I am going to laugh at them. Considering those spikes are on the top of his hand it has to be part of the knife. And if that is a hand piece where is goes all the way around the hand I am going to ask you how in the heck is he holding onto the knife? Because that would be a lot of crap to wrap your hand around and it would make being able to even use the knife so awkward as to be useless. But the knife.... yeah its bad. Redeeming qualities include I didn't draw it. Please start watching Forged In Fire so you have a better reference to how a knife actually functions.
