Mmmmm the twin core I have is much differen than Romex cable. As mentioned earlier I have tried slicing this down like I do for romex but unless I cut 99% through it won't give up easy. So I cut through as far as possible without risk than cut blade up from the end like gutting a fish
until I can grab it and peel it back then trim.
The tool shown before just does what I would normally do with Romex but if I try that it will cut the iner cores as they are solidly encased by the out sheath.
Maybe I'm wrong here but the tool doesn't seem like it would be precise enough to not hit the core whilst cutting nearly all the way through.
Romex is a cakewalk this stuff is an entirely different beast.
When I normally strip sheath from other types of multicore that is formed around the cores like extension cord/leads I score through to 85/90% then bend a little and it tears the remainder, then just pull it off. This stuff won't tear out unyielding its pretty much right through so too much risk of cutting through into core. Once it is cut, if I do it that way, it still won't slide off as it is made to be tight to keep water
I was hoping I was missing a trick as doing it the fastest way I've found so far is tedious and slow. Not bad if its only a couple of wires, but I have a lot to do. The slowness is not as big a deal as the tedious part.
Maybe I'm already doing it the fast way? I hope there's a better way.
