My question is how old does a tool need to be before it's antique or worth anything in the market?
I have a few old Craftsman tools here and they all work because they weren't used constantly. Probably have the manuals for them too. I'd keep them or even use them but they simply don't work as well or easily as new item. The saw weighs like half a ton and the sander is really bad for vibration.....
There's somethings I wouldn't get rid of like arm breaking 1/2 drill or the radial arm saw because they still work fine. Matter of fact the radial arm saw saw more use in the last few months than it did last 20 years.
