Even though i've covered fake stabs and cutting before, a lot of you have been requesting how to make more "medical"-based tools, and I think a good place to expand on my Syringe build from a few weeks ago would be to make one of the most basic medical tools, the Scalpel. 

 

 

I think the best base for this prop is a X-Acto knife, that should by default be a part of your prop building kit already. The issue with using this as a prop is it's obviously a REAL BLADE, it can cut you just as bad as a real scalpel.  So first of all, we're going to have to fix that.

 

 

I got this piece of sturdy cardstock (you could use some poster paper, you just need something that is thin but with some stiffness to it.) Then sketched out the rough shape of the scalpel head. 

 

 

Then using the knife, I cut it out as smoothly as possible. (You don't want a lot of paper fringe coming off of it, since you want it to look like a single piece of hard metal.) 

 

 

Paint both of them with a shiny silver paint. 

 

 

Now just attach the fake head, and utilizing the bulb method that I used in my stabbing and cutting tutorial, and you can safely run it against your actors skin without causing actual harm, or having to file down and ruin a good cutting head.
