Ron,
Most coils I am winding are typically No.22 to No.16 solid copper
magnet wire. I hold the knife vertical to the wired and scrape
sideways so never pressing into the wire - no nicks. Eventually that
does dull the razor blade but they are easily replaced. The knife I
use looks like a miniature box cutter knife.
Actually there is much greater risk using a wire stripper to nick a
wire. Now I suppose if you are winding a toroid with something like
No. 28 the risk would be higher. IN that case probably melting the
enamel with solder iron or into solder pot is preferable.
But good to caution folks about that. I see nicks more likely from
stripping insulation that requires cutting completely around the wire
while pressing down into the insulation to the wire.

Ed's approach is one that I've used from time to time, but let me add one
caution. Be very careful to avoid nicking the wire. It's very easy to do
with fine wire most often by an accidental press where you start removing
the enamel.
The nick will create a weak spot that may fail later. And with that we could
segue back into the question of breaking wires off in gear that is subject
to vibration.
