I have a fair quantity of mains cable, and would like to remove all the
insulation without damaging the cable itself, so fire is not an option.

The cable is ordinary grey sheathed T&E. Removing the earth is easy,
and splits the outer sheath at the same time. Removing the insulation
from the remaining black and red cables is a pain. Using a knife risks
nicking the cable and creating a weak point. Using strippers an inch at
a time takes forever, and the cable is around 70 feet so 140 feet to strip.

For the individual cores, strip a couple of inches off one end and clamp
that in something. Then using a Stanley knife or similar, position the
blade on the underside of a bit of the exposed copper such that its
facing you and just glancing off the wire. Position a thumb lightly on
top of the wire and a bit ahead of the blade. Now pull / wall backwards.
You should find it easy to slice the side off the insulation using the
wire as a guide. Get the angle right and you won't knick the blade.
