this reminded me of another part of a wire splice that is often overlooked as a source of failure. when removing insulation it is VERY important that the wire not be "nicked". even a slight bite into the wire can result in a weak spot and will break if the splice is exposed to any motion, which luckily in most instances is not the case.
add to this some heat shrink insulation... typically just strong enough to support a broken connection... and you are looking at one tough electrical problem to find.
when i cannot find an accurate size wire stripper or NO-NIK cutters on smaller than 28 gauge, i will try to just nick the insulation enough to pull it off rather than to risk touching the conductor with a sharp edge.
