I have been building a tool carrier this week, a wooden box with splayed sides and a handle like every carpenter had a hundred years ago, long enough for my hand saws and my jointer plane, designed for easy carrying. This was supposed to be a simple project, which was my first mistake — but I’ll get to that later, in another post, after I’ve finished the thing. In addition to being more complicated than I realized it has turned out to be more work than I’d expected, for a couple of reasons.
