a nice fine tooth hacksaw blade is the best. would not use anything else."Do not follow where the path may lead, Go instead where there is no path, and Leave a Trail."

32tpi hacksaw blade is the tool of choice0
-
I have only ever used that kind of cutter on metal tubes. I'd be worried that it might crush a carbon steerer.0

That tool is OK for metal - same as a plumbers pipe cutter, no good for carbon.

To get a square cut just wrap a piece of paper with a straight edge around the tube. With the paper wrapped flat against the tube the edge will be square to the tube and you can mark that and cut with a saw.0
-
Just use an old headset spacer and tape it to the tube.
Use the edge of this as your guide

I always use a large cable tie as a cutting guide

I tried cutting down the gap between two old stems clamped to the steerer. It didn't work0

I tried using a jubilee clip for a guide, also didn't work, but as SheffSimon said, it doesn't matter if the cut isn't precisely square.
With a carbon steerer you have to insert a fork bung. This self-positions itself relative to the axis of the steerer, not the end cut. And the top of the bung (or at least, on the one I used) sits proud of the end of the steerer.
Otherwise, as others have said, a new 32tpi blade gives a clean cut. Worth using a dust mask also.

Don't forget to wear a good mask - carbon fibre particles in your lungs are very dangerous - carcinogenic if I remember correctly (not delibrately trying to scare-monger!)Cannondale Synapse 105, Giant Defy 3, Giant Omnium, Giant Trance X2, EMC R1.0, Ridgeback Platinum, On One Il Pompino...0

going against the grain I prefer a harsher cutting blade than a 32tpi hacksaw - with a hacksaw you are gnawing away at the carbon steerer for ages - increasing the chances of going "off" with the cut - a harsher bladecuts through it in many less strokes and then neaten up the cut with a file.
do wear a mask!0 -
I used a hacksaw, but I tried a little pipe cutter thing like that on the bit I cut off and it was fine, if you take your time and only turn it in a little bit every time its won't crush it.And now you know, and knowing is half the battle
