Hi Joe- welcome to the forum
I'm a retired( or thought I was) carpenter that has been amassing tools for years. I have some of my Dad's and Grandad's old hand tools. After using power tools for so many years
I doubt you will be happy using hand tools. I know that I used hand tools many years ago as a youngster with my Dad and never appreciated the amount of labor they took. I'm just not the person who wants to spend a hour doing something that can be done better with power tools in 5 minutes. Probably ,like you I've always had to accomplish as much as well as possible to be profitable. Some members on the forum will disagree with this but I think that good power tools (not Chinese bench top crap) do a very good job. You're right,you can only find a use for so many screwdrivers and you're beater chisels won't work well in wood working.
Tough as nails and nearly as smart
Good tools don't cost- they pay!
