Video: What a day it has been. Time to go into an elective waking coma while this guy makes a crazy-looking knife with skill and precision.
Apparently kiridashi -- the shape of knife being made here -- are often used for pruning bonsai because they have lots of leverage near the tip. Doesn't that seem nice? Just hanging out with a tiny tree... Almost as cool a being a tiny tree. That's the dream, man.
Put on your favourite relaxing jams and zone out. If you pass out at your desk, then, bonus: there will be a sweet knife waiting for you when you wake up.
