24 Arbor Age / June 2014 www.arborage.com If you've got eyes, use them Both eye and eye or Cyclops (single eyed) bridges or tails can be used to create a midline attachment point; and can be of great value when adjustability and minimal strength loss are desired. Pretty much any climbing hitch may be used in this application, though additional turns will often be added to increase security and friction. The use of Cyclops tails will ob- viously limit the user to hitches such as the Blake's or Tautline, while a two-eyed tail opens the whole pantheon of hitches to availability. One that is fairly commonly used with a two-eyed tail/bridge, and relatively simple to tie is the Valdotain tresse or "Vt." As many turns as possible with the given eye and eye are taken in an upward direction on the line. The two ends are then brought together and held secure at the bottom of the turns, as the top turn is rolled down over the other ones, creat- ing the braid or tresse in the Valdotain tresse. This Vt variation also has the added advantage of being much easier to adjust or move after loading than a traditional Prusik hitch. Quickly directional A Quick Hitch is an easily tied and untied simple slip knot in the standing part of the line. While it should not be used for heavy loads, and is not appropriate in all applications, it can be very helpful in sending additional gear, equipment, and even lunches aloft. A properly tied Quick Hitch can help prevent rigging lines from passing through a block or pul- ley inadvertently, and even snaring a forgotten Friction Saver out of a tree. It is formed by creating a loop in the line, and TRAINING & EDUCATION TRAINING & EDUCATION (Clockwise from top left) The steps in tying a Triple Bowline/Blackwater/Lineman's Loop. Three turns around the palm, turn closest to the thumb to the middle, turn closest to the fi ngertips to the "new" middle, turn closest to the thumb to the "new" middle and through, and tied, dressed and set.
