Every once in a while these threads refer back to the use of older tools and days past. I think it would be fun to have people who have never used any of these older tools do so, just so they can better appreciate how far technology has come. A simple thing like a keyless chuck cannot be fully understood unless you have spent time using it's predecessor. Very soon the only cordless tool batteries will be lithium and another bit of old technology will be gone forever. No more memory problems to deal with or charging rituals to ensure readiness. I'm in my fifties and the advancements I've seen in the last ten years have been great, I hope I'm around to see what the next ten years have to offer.
