ECN Forum Forums General Topics of the Trade General Discussion Area Cutting in boxes in panelling

Hoow do you guys cut in an old-work box (sorry for the DIYer term) with wood panelling? I know a matte knife isn't a good idea, as evidenced by a scar my father has from cutting one into a wall for our A/C. So fess up, how do you guys do it?

Thanks,
Ian A.
