props

 I looked into buying props. specifically knives.

I looked through several knives, I decided although the knifes which you can push in will probably be more effective, they will also look less realistic.

Moreover, plastic knives also will look less realistic when on camera.

Therefore, I opted for an all black, rubber knife as I think this will look the most realistic. In addition to this, we could also spray paint the blade silver in order to make it look even more realistic.
