I don't own any Global knives, but I have lusted after them. As far as I
know, they use a harder steel than normal so an ordianary sharpening steel
may not be hard enough. A ceramic or diamond steel might be hard enough
though.

Waterstones are the way to go. A 1000/6000 grit stone should do for most
sharpening, and perhaps a coarser stone for when it gets really dull. These
will give a really good edge if used correctly, Its more like polishing than
sharpening the blade. The stones themselves are pretty soft, so its easy to
nick or scratch them. You should be able to find them in woodworking
catalogues or websites in any country.

To use a water stone, soak the stone in water for about ten to twenty
minutes, and then place it on a towel so that it stays on your worktop.
splash it with fresh water every few minutes while you are sharpening, so it
washes away the metal slivers that have been rubbed off and lubricates the
stone to make it easier to push the blade along. You will get a razor sharp
edge if you sharpen so the angle between the stone and the blade is small.
If you imagine the blade as having a "V" shaped cross section, the narrower
the "V", the sharper the edge, but it gets more prone to chipping then, so
there is a trade off between sharpness and strength.
The difference between using a stone and a steel isn't that much. try to use
a similar angle. The stone will be on the table, so hold the handle of the
knife in one hand and guide the blade with the other. As its usually going
to be a curved blade, make a curved sweep with the blade so that it comes in
contact with the whole edge.

I've never seen a single bevel knife, but I imagine that the whole
"unbeveled"
side is actually the bevel. If its perfectly flat, you can just put the
blade flat on the stone after sharpening the bevelled side, and take off
the burr. A 6000 grit stone will give
a near mirror finish. For the final sharpening you can use a small stone
called a Nagura. Rub this over the 6000 grit side a few times and the grit
from the Nagura will make it even finer for the last few passes.
