I really like this shot. That knife grinder in action looks great. The overall photo has a nice old school feel to it. It makes me think that the person in this shot really makes his living using this tool of the trade. Great job, I voted when voting began and gave you an 8!
The focus is very poor on this one. If you had downsized the image to, say, 640 pixels the resolution would have been improved. But they are certainly good tools of the trade. Just need to photograph them better.
