Kryston Non-Slip Loop

Kryston loop · Kryston non-slip

A fixed loop that ties a hook or lure to nylon monofilament. NetKnots reports it failing in fluorocarbon well below the line's rated strength.

Finished structure

Drawn from a rope model of this knot: which strand passes over which comes from where the rope actually lies.

  1. Tie a loose overhand 15 cm from the end, tag over the line and out through the loopA loose, open overhand knot is tied in the line well up from the end, with the tag end leaving the loop and hanging free below it.
    1Loose overhand
    2Tag end
    Move 1 of 1Tie a loose overhand 15 cm from the end, tag over the line and out through the loopYou should now see: An open overhand about 15 cm up the line, its hole wide enough for two passes, and the tag hanging free below it.

    Step 01

    Tie a loose overhand knot about 15 cm (6 in) from the end of the line, crossing the tag end over the standing line and out through the loop. Leave the overhand open.

    You should now see

    An open overhand about 15 cm (6 in) up the line with a hole wide enough to pass the tag through twice, and the tag hanging free below it.

    If it goes wrong

    Pulling the overhand snug as you tie it. The hole closes up and there is no room to bring the tag back through twice later.

    Fix: Work the overhand open with a fingertip until the hole is wide again. If the tag has become too short to finish, cut the knot out and start again from a fresh end.

    Why: NetKnots reports this loop holding well in nylon monofilament but failing in fluorocarbon well below the line's rating, so tie it in nylon.

  2. Pass the tag through the hook eye, keeping the overhand open above itThe tag end runs from the open overhand down to the hook and passes through the eye, hanging below it.
    1Tag through the eye
    Move 1 of 1Pass the tag through the hook eye, keeping the overhand open above itYou should now see: The tag through the eye and hanging below it, the overhand still open, and the line between them not crossing itself.

    Step 02

    Pass the tag end through the hook or lure eye, keeping the overhand open above it.

    You should now see

    The tag through the eye and hanging below it, the overhand still open above, and the line between them lying flat without crossing itself.

    If it goes wrong

    Letting the line twist on its way to the eye, so it crosses over itself between the overhand and the eye. The two sides of the lure loop look uneven.

    Fix: Pull the tag back out of the eye, let the line untwist until it hangs flat, then feed the tag through the eye again.

    Why: The hook or lure goes on before the tag returns through the overhand. Once the return passes are made, there is no way to add it without starting over.

  3. Bring the tag back through the overhand from behind, the side opposite the lineThe line leaves the overhand over the left side of its loop. The tag comes back from the eye and goes in behind the lower left side, the opposite face, through the loop from behind, then out and down in front of the loop's bottom strand.
    1First pass, from behind
    Move 1 of 2Bring the tag back through the overhand from behind, the side opposite the line
    Pass the tag through the same way a second time, then pull the line to draw the box smallThe tag goes under the loop's bottom strand, up behind it and through the loop from behind a second time, then out over the loop's lower right corner and away to the right, the same way as the standing line. It has gone round the lower rim of the loop twice.
    1Twice round, through the loop
    2Tag out to the right
    Move 2 of 2Pass the tag through the same way a second time, then pull the line to draw the box smallYou should now see: A small box of line behind the lure loop, drawn down but not tight, the tag leaving it to the right, the same way as the standing line.

    Step 03

    Bring the tag back through the overhand from behind, the side opposite where the line came out, then pass it through the same way a second time. Pull the standing line to draw the box small without tightening it.

    You should now see

    A small box-shaped closed loop of line sitting just behind the lure loop, drawn down small but not yet tight, with the tag pointing toward the lure.

    If it goes wrong

    Entering the overhand from the same side the line came out, or making one pass instead of two. No small box forms, and pulling the standing line makes the lure loop slide smaller.

    Fix: Pull the tag back out of the overhand and make both passes again from behind. If the box stays large and loose, pull the standing line a little harder before moving on.

    Why: The two passes lay the tag around the overhand so it is gripped when the knot closes. A pass from the wrong side leaves the tag free to run, and the loop behaves like a slip knot.

  4. Hold the box top, pull the tag to size the loop, wet it, then pull tag and lineThe box has been slid toward the eye and drawn smaller, with a small open loop through the lure's eye. It is drawn opened out so its crossings can be seen: the tag leaves it to the right, below the standing line.
    Move 1 of 1Hold the box top, pull the tag to size the loop, wet it, then pull tag and lineYou should now see: Pulled tight, a compact knot close behind an open lure loop of the size you chose, the lure swinging freely in it.

    Step 04

    Hold the top of the box and pull the tag gently to slide the box toward the eye until the loop is the size you want. Wet the knot, pull tag and standing line together while holding the lure, then pull the standing line.

    You should now see

    A compact knot sitting close behind an open lure loop of the size you chose, with the lure swinging freely in the loop after the last pull.

    If it goes wrong

    Tightening before the loop is sized, or pulling the standing line first. The knot closes wherever the box happens to be, and the loop stays at that size.

    Fix: If the loop has closed at the wrong size or down onto the eye, cut it off and tie it again, sizing the loop before you wet and tighten.

    Why: Pulling tag and standing line together closes both passes evenly. The final pull on the standing line alone seats the knot in the direction a fish will load it.

  5. Add an optional half hitch if you want one, test the loop, then trim the tagThe finished Kryston loop, shown without the optional half hitch and drawn opened out so its crossings can be seen: a short trimmed tag leaves the knot to the right, below the standing line, and an open loop runs through the lure's eye.
    Move 1 of 1Add an optional half hitch if you want one, test the loop, then trim the tagYou should now see: A short tag beside the knot, the lure loop still open, and a knot that did not move under the test pull.

    Step 05

    If you want an extra hitch, tie a half hitch with the tag around the standing line, wet it and pull it tight. Give the loop a firm test pull, then trim the tag close to the knot.

    You should now see

    A short tag beside the knot, the lure loop still open, and a knot that did not move under the test pull.

    If it goes wrong

    Trimming the tag before the test pull. A loop that shrinks or a knot that slips under your own pull goes out on the water unnoticed.

    Fix: If the loop shrank or the knot moved during the test pull, cut it off and tie it again rather than adding more hitches.

    Why: NetKnots doubts the half hitch adds much, and many anglers leave it out. The two passes through the overhand are what hold the loop open.

Fixed-loop family

A loop that stays the size you made, with a return that cannot cinch.

  • !Loop cinched around the hardware — action is dead
  • !Return path reversed, so it becomes a slip loop
  • !Fluoro in a lock that only behaves on mono
Fails when
  • !Tied in fluorocarbon, where NetKnots reports it failing well below the line's rating
  • !The tag went back through the overhand from the wrong side, leaving it free to run so the loop slides smaller
  • !Only one pass was made back through the overhand, so the loop slides smaller when the standing line is pulled
Geometry

  • Reversed return path

    A slip loop, not a Kryston

    The return is the non-slip lock on mono — reverse it and it cinches · step 03

  • Loop closed around the hardware

    Wrong sequence; action is dead

    Size the loop, then lock, without trapping the hook in a tight eye · step 02

  • Fluoro substituted for mono

    This lock is a mono knot — fluoro will not behave

    The Kryston non-slip we cover is mono; fluoro is a different family · step 01
