.... how does one produce such vertical walls and right angle junctions?
With a treadle lathe, no less.It was probably made using a sharpened tire iron in a Cambodian jungle by some bare footed guy. Those guys can do amazing work.
...... or even preferred!A sweeping rounded bottom, or a radius corner, or a square corner are all OK.
While I use my skew for a whole lot of tasks, this is one where I would not. In my hands, the skew has a tendency to drift towards the long point when used flat, and I would have an easier time getting a truly straight side with a scraper. YMMV.A sharp skew is more then capable of cutting boxes on a lathe with that design. Once you get the wall at 90 degrees you work your way into the box using the back edge of the skew to align to the side of the box. The bottom can be squared up by creating a flat in the center of the bottom and then working the cutting edge of the skew outward in several passes until you reach the flat bottom across the entire bottom of the box. Meeting the bottom and the side with a clean cut takes practice for that 90 degree corner..
.... I then use a skew that was ground to a 90 degree angle across end....
I knew this was something that you could answer. Plunging in with a straight skew is how I used to do it. Unbeknown to me at the time, it is an acceptable technique for cutting end grain.A number of tools can do it. If you use a square nosed scraper that is tapered on the left side, and on the bottom it is simple, but if you use one that is, a 90/90 grind, you will have trouble at the bottom because both cutting edges will be hitting at the same time. Fairly simple to go straight down the wall. Generally you need your tool rest above center so only the top corner edge of the scraper will contact the wood, where if you are on dead center, both the side edges of the scraper will be contacting the wood and you will drift to the middle as you go down. I had problems making square edges for a while until I discovered NRSs (negative rake scrapers), and a skew is a NRS, or the other way around. You can have a bunch of them with 90/85 nose profiles, or 90/85 with a radius, or rounded corner and gentle sweep for the bottom, or even more round nosed, depending on how you want the bottom...

Glad you were a good student and didn't get thrown out.Oh, you youngsters. A skew that is straight across is a chisel. It's one of the tools we had available back in Mr. Higus' Jr high shop class in 1962. Our high school shop has several as they get donations and never throw anything out.
