How to Tie the Lapp Knot - Synched Around an Object

Usage

The (Slipped) Lapp Knot is a fairly unknown but super useful quick-release anchor knot. It's a simple anchor that can be used for tarps, guylines or other fastening points with an incorporated quick release. For tarp and tie-out setups, a dedicated line like the 1.8mm Reflective Guyline makes a great pairing for it.

Why Learn the Slipped Lapp Knot?

This knot provides an easy-to-tie solution for adjustable fastening and securing items with the added benefit of quick release. It is a practical choice for everyday applications and offers greater adjustability compared to similar knots. It's also one of those knots that clicks fastest with practice cord in hand — the Knot Tying Kit is built for exactly that.

History

The Lapp Knot has been used since 1892 under various names such as False Weaver's Bend and Girdle Knot. It was widely utilized by native cultures across America, Lapland, Africa, and Australia (see Wikipedia's Lapp knot entry). The slipped version is featured in Ashley's Book of Knots as a decorative knot for bathrobe cords.

Security Level

The Slipped Lapp Knot provides moderate security with an easy release function, making it ideal for non-critical applications requiring frequent adjustments. Its holding power is strongly dependent on the rope's material, diameter, and the type of load, so always verify it in the specific cordage you intend to use before trusting it — a line it grips well in one material can slip in another.

Downsides

• Can Loosen: If not tied correctly. Because this is a slipped knot, a mistied tuck can leave you holding a slip knot that spills under load instead of gripping — check that the quick-release bight is seated the right way before you rely on it.
• Not Suitable for Heavy Loads: Best used for light to moderate applications.

Structure

1. Wrap the working end around the object.
2. Pass the working end over and under the standing part.
3. Form a bight and pass it through the loop.
4. Tighten the knot by pulling both ends.
5. To release: Pull the free end firmly.

If the over-and-under crossing in steps 2–3 is where this one falls apart for you, the Knot IQ app lets you rotate the Lapp Knot in 3D, slow it down, and step through each pass at your own pace.
