Have you ever seen someone actually grinding an axe?
I haven't.
I've met many people who say they have an axe to grind. Where are they getting their axes?
I have two axes at my cottage. One is really what's called a wood splitter, but it totally has the personality of an axe. I've never had to grind either one.
I'd say if you have a axe to grind then you're buying lousy axes.
That's my life lesson for you – if you have an axe to grind then buy better axes.
