Our sharpener ran the pad of his thumb over the edge of the blade. "It's got a few hours left." He does this all the time, with everyone. Run his thumb over the blade and say 'It's got a few hours left". It's quite a show.
I mean the thumb gets out quite a bit, goes to parties, meets chicks (or at least chick's skates), hangs out with famous people.
I call it the Magic Thumb.
The Magic Thumb Party's Hard
And well deserved!
