I think that multiple tools could be intimidating to new woodworkers. (IE I could never have all the tools I need) the less shown the less intimidation. I agree that it was fun looking at all the tools.
I loved all the tools hanging behind Paul. I don’t think a new woodworker should be intimidated. He tells you what you need for each project. Sometimes I see a tool and wonder how it’s used and why he keeps it around. Then he uses it and gives you a history and thus a better understanding of how little woodworking has changed.
