That's a Manix 2, a Tenacious, and a Paramilitary 2, all different designs, and the tenacious is a $30 knife while the other two (in S110V steel as these are) retail for around $250, they have slightly different blade shapes, and all 3 have entirely different locking mechanisms, but they do look a lot alike
So I legitimately can't tell for sure if that's sarcasm or not
@th3r0n its clear you prefer that type of blade...just my way of pointing it out. I know a man that carry's throwing knives instead of a handgun. He can access them and get one stuck into his target before a guy standing next to him and clear leather with his pistol. Its amazing to see him do it.
