10 Degree Step Stool
With legs canted at 10º, a slot for hanging is also bored at 10º. When hung on an archetypical nail that is pounded into a wall at a slight upward angle, the angled slot allows the step stool to lay flatly against the wall, in harmony.
The piece's signature joint is a through tenon with a cheek also angled at... you guessed, 10º.
