About the above image: 28 1/2" overall. 22 5/8" unsharpened blade. Brown wood handle with antique brass finish knuckle guard. Pistol is attached to side of aword and has an antique brass finish.
Now, that doesnt solve the mysery does it?
Now look at the below image...
This has been mentioned before, the little barrel up the side has continuesly dissmissed by people as "Decoration, it could't work." but now there is proof that it is possible and is in the right place aswell.
To me that seems pretty good proof that is what the trigger does, as the Gunblade cuts it fires of a bullet from the barrel into the targets body, therefor causing much more damage.
