Snyder Slider (Fig. 39)

FIGURE 39. A-E. Snyder Slider.

The Snyder knot has been termed a flip-knot because tension applied to the loop once the knot has been
pushed into place causes the knot to “flip” configuration to a locked form (16 ,41 ).

 The post limb should be one half the length of the loop limb.
 Wrap the loop strand behind and over the post strand (Fig. 39A ).
 Hold the intersection of the loop strand and the post between the thumb and index finger of the
non-dominant hand.
 Wrap the tail end of the loop strand behind and around the combined post and loop strands closer
to the joint than the initial loop (Fig. 39B ).
 Bring the tail end of the loop strand behind the loop limb and though the parallel post and loop
limbs (Fig. 39C ).
 Tension the knot by gently pulling on both the loop and the post strands simultaneously. Do not
pull too hard on the loop strand or the knot will lock prematurely.
 Advance the knot by pulling on the post limb while pushing the knot with the knot pusher on the
post strand (Fig. 39D ).
 While maintaining tension on the post strand and using the knot pusher to keep the knot in place,
pull the loop strand to lock the knot (Fig. 39E ).

Although the initial description of the knot did not include locking with half hitches, our experience shows
that locking with half hitches improves knot security (unpublished data).
