Which is completely and utterly useless for most trades these days. The job has changed a bit since the 1980s with the move towards power tools and higher productivity. In fact advances in cordless tool technology over the last 10 to 15 years have changed things faster than in the previous 40 or more years. That's why even those of us who made these "classic" tool have abandoned them in favour of open top totes, pull along boxes, and yes Systainers and their ilk. They are much more practical
That doesn't mean to say I don't appreciate the work that goes into a dovetailed joint
I doubt that I've seen anyone walk on site with one of those in more than 30 years other than the occasional French polishers (who tend to have a fairly minimal kit). It's because they no longer work for the majority of trades. I certainly abandoned mine long ago - too small, too inflexible in what it could carry, too small for power tools
No mention there of cordless tools, caulking guns, foam guns, nail guns, pinners, trim routers, etc. I see. The old ways are the best? The old ways are often unproductive and not a lot of use when you are dealing with modern materials like cement fibre board or sheet materials. Great for some things, but not so many things. Even when sistering joists, doing beam end replacements or replacing damaged king posts tools like angle drills and powered saws are more productive than hand tools. It's called progress
