Reverse Engineered Object: Selecting an Object

To help better my skills in using Rhino, I have chosen and object (or two) that i will reverse engineer and attempt to build using what skills I have, and will learn while trying to render them digitally.

The first object I chose, and am more inclined to render is a small key-chain compass.

The second object I was looking at, is a pair of scissors used for cutting hair.

I will soon finalize my decision on which object I will be doing, and begin to render it digitally.
