Specter's Ripper

I made Specter's Ripper, I added an extra handle under the blade holders to have better grip. Unfortunately I couldn't make the blades move from inside out because the program I used sometimes doesn't want to make things work. This would go great if you have the rest of Specter's outfit, if not at least you've got yourself a ripper. Please tell me if I did something wrong on it. :)
