0.8mm and below can be cut with a decent pair of scissors.
I'd agree that the hacksaw method is the way to go if you don't have a guillotine - clamp the board to the bench edge with a sheet of wood & it's easy to get a straight cut - keep the blade at a shallow angle.
Noting beats a guillotine though.

Tin snips work great too.  Sears sells a great set.

I have access to a guillotine style (aka "massive scissors") pcb cutting tool.  But I'm worried that it's going to short the ground and power planes together in my 4 layer pcb?

I either use the good old hacksaw + file or if I can't be bothered score the PCB along a metal ruler with one of those cheap cutter knifes with the snap-off blades from both sides. Then clamp the PCB along the cut into a vice or on a table edge and just snap it off and file the edges down.
The Dremel stays in it's box for simple straight cuts, far too messy and noisy.

If you have any access to a milling machine, you could use that.  I have had great success when putting multiple designs on one board, then cutting them out on my end.  I use a 1.5mm end mill at the fastest the mill will go.
