Ron did a good job on screwdrivers. What he neglected (forgot, didn't think of, afraid to say ( :) ), is if you wanted to make screwdrivers for the markets what would it cost you to tool up and produce. I don't think you want to know that. If you make them yourself, one at a time, the cost gets astronomical. They do not make 100,000 of them a year, which is what brings the cost down because you can amortize setup costs over 100,000 instead of 250 or so a year. There isn't a large enough market for the tools to warrant that level of production. Newton
