The "crew" are my tools. The team varies and is always being fine tuning, being assembled from the best I have--my 10" Makita Compound Miter Saw, a tape measure, a good screwdriver with variable tips, a Makita cordless drill, a hammer (borrowed from my husband), and a tri-square/level.
I want to prove a point to myself as one of the Things I get to do today: Shiny, clean tools work better than rusty, dirty ones. That means for this tri-square to stay on the job with me, it needs to clean up its act. Since I'm responsible for my crew, I need to clean up its act. During the steel-wooling of the ruler section, I pondered my hypothesis about clean vs. rusty. The marks on the rule do not change with the surface condition; however, it is harder to adjust accurately if it's rusty. So the tool actually does work slightly better when it's clean.
More important, however, is how one feels when using the tool. Frustrated, unsure, fumbling, grumpy, impoverished, unclear; or confident, abundant, masterful, accomplished, smart, professional? The thought and the attitude of the person determines how skillfully the tool is used. I work better when I wear makeup, and I work better when my tools look sharp and work well.
One final observation: Look-like-new can be kept that way. Maintain your crew and they'll work faithfully for you forever. You don't want the "before" and "after" labels above to be reversed. Few tools can be salvaged as easily as this vintage Stanley Handyman No.H1222 1/2.
