a pipe cutter will give the best cut and you can use it on an aluminium alloy steerer with no problems; I have used it on a steel tube but it will ruin the cutting wheel failry quickly but can be done - better to use the cutter to mark the tube then use a fine toothed hacksaw. The same can be done for a carbon steerer but the dust produced when sawing is bad so do it outside.
measure twice and then measure again as once cut, you cannot lengthen the steerer.
For A-Head fork/stems the cut doesn't have to be really straight as the end lies just below the rim of the stem and the top cap contacts with the top of the stem.
Wonky steerer cuts are irritating and unnecessary. You'll need a half tound file, a hacksaw with a straight fresh fine blade, a handlebar stem and a headset spacer you're prepared to sacrifice. Using the stem clamped to the steerer as a stop, place the spacer up against it to act as a blade guide. Use the file to deburr the cut edge - unless its a carbon steerer where you use a bit of medium wet and dry - use it wet to keep the dust under control.
