I think cutting with a knife is the best way (I use the Dremel only for traces: I remove only the copper, without removing the PCB).
You make one only cut then you put the piece on an iron solid wire (2 mm at least) and press!

I personally use a Dremel tool with a cutoff wheel. Takes some
practice on cutting with the cutoff wheel without shattering it but
once you get used to it I thing it is the cleanest and easiest.
