Reverse Engineered Object: Rendering the Object Part 1

I have begun to construct the scissors in 3 dimensional form, starting with the screws.

Here I made the screw using spiral, and sweeping a triangular shape following the spiral. Combined with a few cylinders, the screws begin to take shape.

Adding the rounded top to the screw.

And finally adding the indent for a screwdriver head.

Almost forgot to ad a slight rounded bottom to the screw

First screw is done, aside form my difficulties in combining the shapes using the command BooleanUnion. Perhaps I will have to reconstruct the screw to do so?

Moving on to the next screw

The screw part is done, same method as the first one (also same problem combining the parts).

I am a bit unsure as how to create the texture for the piece that the screw is attached to. I will set this aside for now.

From the screws, I moved on to trying to construct the blade of the scissors. I started with the main shape of the blade, although I am a bit unsure on how to approach making the blade more blade like. I think i still have some angles and measurements to do.
