Interesting. My Dad used to say you can tell the quality of a man's work by the condition of his tools. I have always found that to be true. In addition, I have found cleanliness of my work area to be directly related to safety so I keep my shop area picked up, swept and organized as much as possible. After every work session, I tackle the clean up. Less worry about fire then, too. In an aside, (maybe this doesn't go in this topic but I'm going to say it anyway) I've have been noticing pictures of many smith's tools on this site and other 'smithing websites where the heads of fullers, hot sets, chisels, drifts, punches, cold sets and the like are dangerously flared from hammer blows. Speaking as one who had an ophthalmologist grind out a piece of steel from a pupil, you don't want to go through that; so, dress those flared tool ends after they begin to expand and prevent that painful occurrence.
