TYING OFF

High tensile wire can be "tied off" to brace posts using knots, nicopress sleeves or wire vises. 

It is easier to use a lower strength wire like 170 vs 200 to tie off.

HALF HITCH KNOT

High tensile wire may be stiff, but you'll find it relatively easy to make a simple half hitch knot to fasten the wire

to brace posts. The break strength half hitch is over 60% of the
break strength of the wire (about 1100 pounds). To tie a half hitch:

1.  Pull about 3 feet of wire around the post.
2.  Bring the end of the wire underneath and back over the line wire.
3.  Bring the end down between the post and the wire that you
      just wrapped around the post.
4.  Bring the tail under the wrap and over the line wire.
5.  Make two tight wraps with the tail around the line wire.
6.  Break or cut off the tail. Cutting leaves a rough surface.

Breaking wire will leave a smooth surface. To break off excess wire:

1.      Put a 90° bend in the wire about 6" beyond the knot. 

2.      Grasp the wire just beyond the bend and crank it parallel
 to the fence line (back toward the post or splice). The wire
will snap right off.

The faster you work, the easier the wire is to break. High tensile wire gets hot when worked slowly. When hot, the wire becomes more difficult to work and break off.
