Depth of cut seems to be critical, too shallow and it won't fold, too deep and, oops, let's try again. And I am surprised that the thin grain left after the cut doesn't just break or split when folded. Seems like you would need to steam the fold area but apparently not. I don't make so many shop drawers that it would appeal to me. For the few I make I will stick with hardwood and dovetails with my Leigh jig. But I will give him his due, this guy was really thinking outside the box...
