Do you know how your tools work? And is it hurting your ability to do better work?

Over the last year I have come to realize when I don't understand how my tools work, or how to set them up I don't always get good results.

I also tend to wonder if I am bad at whatever the task is I am doing. I think being able to clean, maintain, and restore tools is a skill everyone should develop so they can get maximum effectiveness and life out of their tools.
