Knot Tying- Part 1

Clove Hitch

The clove hitch is an anchor knot that can be used in the middle of the rope as well as at the end. The knot must have constant tension on it once tied to prevent slipping. It can be used as either an anchor or middle of the rope knot, depending on how it is tied.

a. Tying the Knot.

(1) Middle of the Rope.

STEP 1. Hold rope in both hands, palms down with hands together. Slide the left hand to the left from 20 to 25 centimeters.
STEP 2. Form a loop away from and back toward the right.
STEP 3. Slide the right hand from 20 to 25 centimeters to the right. Form a loop inward and back to the left hand.
STEP 4. Place the left loop on top of the right loop. Place both loops over the anchor and pull both ends of the rope in opposite directions. The knot is tied.

(2) End of the Rope.

Note: For instructional purposes, assume that the anchor is horizontal.

STEP 1. Place 76 centimeters of rope over the top of the anchor. Hold the standing end in the left hand. With the right hand, reach under the horizontal anchor, grasp the working end, and bring it inward.
STEP 2. Place the working end of the rope over the standing end (to form a loop). Hold the loop in the left hand. Place the working end over the anchor from 20 to 25 centimeters to the left of the loop.
STEP 3. With the right hand, reach down to the left hand side of the loop under the anchor. Grasp the working end of the rope. Bring the working end up and outward.
STEP 4. Dress down the knot.


Two-Loop Figure-Eight


The two-loop figure-eight is used to form two fixed loops in the middle of a rope. It is a middle rope knot.

a. Tying the Knot.

STEP 1. Using a doubled rope, form an 18-inch bight in the left hand with the running end facing to the left.
STEP 2. Grasp the bight with the right hand and make a 360-degree turn around the standing end in a counterclockwise direction.
STEP 3. With the working end, form another bight and place that bight through the loop just formed in the left hand.
STEP 4. Hold the bight with the left hand, and place the original bight (moving toward the left hand) over the knot.
STEP 5. Dress the knot down.

Bachman Knot


The Bachman knot provides a means of using a makeshift mechanized ascender. It is a specialty knot.

a. Tying the Knot.

STEP 1. Find the middle of a utility rope and insert it into a carabiner.
STEP 2. Place the carabiner and utility rope next to a long climbing rope.
STEP 3. With the two ropes parallel from the carabiner, make two or more wraps around the climbing rope and through the inside portion of the carabiner.

Note: The rope can be tied into an etrier (stirrup) and used as a Prusik-friction principle ascender.

b. Checkpoints.

(1) The bight of the climbing rope is at the top of the carabiner.
(2) The two ropes run parallel without twisting or crossing.
(3) Two or more wraps are made around the long climbing rope and through the inside portion of the carabiner.

Stay Prepared! Stay Alive!
