Wow..never thought about that. Did you knock the frets loose first?
That's been my fret removal tool for several decades, a large toenail clipper, slightly reground. I have a cheap 1/4" chisel, reground to a round edge, that I tap under each fret end on the bass side, to lift it just a hair, then walk across with the tool, after hitting the fret with a soldering iron.
I've never found any tool that works better than this.
