It reminds me of the Final Fantasy VIII gun blade where you use that for Lion Heart. Shing…! Bang! Bang! The one above is called G.R.A.D., a knife gun that holds five .22-caliber bullets in a revolver-like barrel and will fire at the squeeze of the handle. So if you had a gun, and your enemy had a knife, doesn’t mean you’ll be the winner of the match, check if he holds a knife gun. Demonstration available after the break.
