Seems to me Norm made a corner cupboard and his plans are still available as far as I know. May not be exactly what you are looking for but easy enough to modify.
Slightly off topic but not much. My father made a couple of knives one of which traveled with his brother during WWII. He made them from old files which I think are pretty brittle. He was a machinist so maybe he treated them somehow so not so brittle. Anyway to tell short of smacking them...
I use a melamine covered piece of shelving from the big box store. Without looking it is about 12 inches by 36 or 48 inches. I also put wax on it every now and then.
I'm a pretty basic hobbyist. Enjoy spending the time but the body is breaking down so I only spend a few hours a week in the shop. Used to make things to donate to Special Olympics and the Fragile X Foundation craft fairs and such.
