Today I have blown two nuts.
One after the other.
The first was carelessness—I cut a string-slot too low. It happens, but it's annoying. The second was extra carelessness as I was rushing to make up time lost by screwing up the first nut.
There's a life lesson here, kids. If you've already ruined a nut, don't risk another one by going at it too quickly.
