I'm with Matt and would be a bit cautious removing the tail.

When they swage larger diameter wires (I'm talking 30mm here), There is always a tail out of the swage so you know if it is starting to fail as the wire slides into the swage. The idea of swaging is not just the friction and compression of the swage but the collar like effect the swage has with the blockage of the tail.

Some swages even drive a wedge into the end of the tail to increase this effect (think of an axe handle). I compare it like pulling a nail out of a board vs pulling a rivet out.

The loads on these wires are pretty small, but they can experience large shock loads at times in collisions and capsizes. The effects if a wire goes are pretty catastrophic also. Makes me think I should check my wires next time home.....

Luke
