I really enjoy working with my hands.  So much so that I became a mechanic.

Mechanics are is a great trade and craft to have. I like using tools to repair all types of machinery.

What's your favorite tool to use?
1_Wizard
All types. It takes using many. A mechanic is certified typically by a regional government power or by a trade association.

Yeah, I keep up on my certifications.  I prefer the fairly simple tools. A ratchet is my favorite.

Most mechanics specialize in a particular line of work. Wether it be bicycle, motorcycle, auto, industrial, or diesel.

I work as an auto mechanic.  What's your specialty?

Same. Since you are so curious about mechanics, there are lightweight and heavyweight mechanics.
