One can make accurate cuts with a track saw good enough for cabinets. In the pre Great Depression days carpenters built cabinets (often on site) with a hand saw.

You can also use a hand plane on the edges of good plywood.

I did a video on my YT channel about installing a mortise lockset with only hand tools just to show how it was back then. With modern tools I used to do 30 2-1/8th" style in an 8 hour day. I think 8-10 a day would have been the goal in the early days.

That's what modern tools do, make it easier and quicker. Not necessarily better.
