Researching for villain props

I made some research and experimented with some of the possible props that our villain or killer could use at the end of the film opening. I searched for the most common and conventional horror props, in order to match our genre and I made a small poster on some of the characteristics of each of the possible props and their advantages and disadvantages in order to make a final decision having a wide overview of all the possible effective props.
