slice like a goddamn hammer

[Mike Hussey]

I don't lose. People who bet on me to lose, lose. They lose big. You come at me, you need to know when I move, and I move quick. I slice like a goddamn hammer.

What does "slice like a goddamn hammer" mean?

Hammers don't slice- they pound and crush. I guess the person is being sarcastic- their attack is on all fronts and not subtle.
