When someone saw the above photo they asked me. Do you have a “color code” for the bands on your tools. I often get this question.
No I don’t. Long ago I started off in that direction. But, I just did not have the necessary discipline. I quickly ran out of colors (different shades of the same color are not good enough) and things get fouled up when you reuse a handle that was on a scraper for a new gouge. Etc.
