I use a big lead hammer on the concrete floor, and a sharp knife.
I lay the AN line on the lead, and then a sharp knife on top, and cut it with just one hammer blow, it will make a nice clean cut.
The braided steel, will need some massage to get round again.

I learned this method from a Top fuel racer.

I have heard cutting with a 1mm super thinn cut off wheel, also works great.
Never tried a plier tho.
