hi,
Vero board is also known as copper strip board, ie: the hole pads on Rows are linked by the copper strip.
Dot boards are only copper pads, which are not linked by copper track.
You can cut Vero board, use a junior hacksaw and cut along the holes, after cutting, file off any copper whiskers on the edges.
Or
you can use a utility knife, well score BOTH sides of the board along the holes and snap off along the score, use the edge of the bench.
If you don't score both sides its possible that you will lift/tear the track off the board.
