I agree, the dremel works great. After cutting cable housing, sometime I cut too fast which generates some heat that softens up the teflon. I just stick an old spoke inside and wiggle it around and problem solved. Using the cable cutters which bends/distorts the metal under the teflon and you still need to correct that by filing or grinding and some bending to get a smooth exit point. Using the dremel saves time and a lot of work and provides a cleaner cut. a dremel pays for it's self in no time.
my recommendation is a dremel
