The Field knot (11 ) is a locking knot that is a modification of the Savoie-Modified Roeder. Although a
locking knot, the originators of this knot recommend further reinforcing it with a series of three half
hitches.

 The post limb should be one half the length of the loop limb.
 Throw an overhand loop over the post strand (Fig. 35A ).
 Throw a second loop around both the post and loop limbs. Be sure to leave a small “hole” in the
loop prior to throwing the second loop (Fig. 35B ).
 Throw a third loop around both the post and loop limbs (Fig. 35C ).
 Wrap the loop limb around only the post and bring it away from the joint (Fig. 35D ).
 Pass the tail of the loop limb between the post strand and through the hole created in step 3 (Fig.
35E ).
 Loosely tension the knot but do not pull on the loop limb or the knot will lock prematurely (Fig.
35F ).
 While pulling on the post limb, push the knot into the joint with the knot pusher on the post strand
(Fig. 35G ). Once the knot is seated with the knot pusher, maintain pressure on the knot pusher
and pull on the loop strand while keeping tension on the post (Fig. 35H ).
 Lock the knot with a series of three alternating half hitches with post switching (Fig. 35I ).

o Throw an underhand loop on the original post. Tension with the knot pusher.
o Switch posts.
o Throw an overhand loop over the new post. Tension with the knot pusher.
o Switch posts.
o Throw an underhand loop on the original post again. Tension with the knot pusher.
