Anyone ever cut the 'ears' off of Mark IV FU-3 footswitch?

[rockhound76s]

Downsizing my pedalboard, and I'm at the point where the Mark IV footswitch would fit perfectly if not for the ears sticking out on either side. Since I never use the ears, I wanted to shear them off. Anyone have success doing this? What cutting tools are needed? (Specific links where to purchase would be appreciated).

Pardon my ignorance, but I'm a novice working with metal shop tools, but I figure this can't be too difficult to do.

Thanks in advance.
