[No glue, no nails, no visible joints. The Japanese are insane.] [1] [2]
There's a Japanese style of woodwork called sashimono [3] where no nail or glue is used when making joints. Just intricate cuts using scores of custom saws and planes (no power tools here) to make blind joints (joints that do not show).
It's insane.
And it's incredibly beautiful.
I asked both Bunny and her brother (who's currently visiting) if they would take up sashimono, and in unison, both said “Oh XXXX no!” They're perfectly happy to use power tools and typical jointery for their woodworking projects, not that I blame them.
