Reverse Engineering Object Selection

 First Idea: 

My Old Stapler/ The Great Stapler/ Stapler I that has gotten retired for quite some time now: 

I originally wanted to pick my newer stapler, then I remembered that I still have this old one somewhere in my drawer! I am interested in the shape of this one just because I have always thought it looks kind of odd! It looks like a dinosaur.

Second Idea:

The New Stapler (Stapler II), so I decided to also choose this one because with the first look, anyone can actually name what this object is 

Third Idea: 

My Utility Knife from work! This knife has helped me open so many boxes and I simply would not be able to survive without it. I have been using this same brand of knife for the past three years so yes we have a strong bond

Forth Idea :

My very nostalgic pencil sharpener! I grew up with this sharpener and to this day it has been the best one I have ever owned! to be honest I wanted to add this one here more as an honorable mention because I don't think I have the heart to mess with it or open it up. I would if I had two though!
