How to Tie the Bag Knot (Slipped)

 

Usage

The Bag Knot (Slipped), also known as the Slipped Miller’s Knot or Slipped Sack Knot, is commonly used to securely tie the neck of bags or sacks, such as grain sacks or camping gear bags, with a quick-release feature. Compared to the standard Bag Knot, which is tighter but harder to untie, this slipped variation allows instant release with a tug, making it ideal for temporary closures.

History

The Bag Knot (Slipped), a variation of the Bag Knot, likely originated in agricultural and maritime contexts where securing sacks of grain, flour, or cargo was essential. Referenced in The Ashley Book of Knots (#1242) as the Miller’s Knot or Sack Knot, its slipped adaptation reflects the need for quick access to bag contents. Its use in modern camping and utility tasks highlights its simplicity and effectiveness for temporary binding.

Security Level

The Bag Knot (Slipped) is reliable for securing light to moderate loads, such as bag necks or small bundles, when tied correctly. Its quick-release nature makes it less secure than the standard Bag Knot for prolonged use but ideal for temporary closures. For slippery twine or heavier loads, ensure proper tension or consider a more permanent knot.

Downsides

• Limited security: Less stable for heavy or prolonged loads due to quick-release design.
• Tension-dependent: May loosen if not under consistent pull or if the bag shifts.

Structure

1. Wrap the rope or string around the neck of the bag, crossing the working end over the standing part.
2. Form a loop by passing the working end under the standing part and around the bag again.
3. Instead of passing the working end through the loop, form a bight with the working end and tuck it through the loop.
4. Pull the standing part to tighten the knot, ensuring the bight is accessible for quick release.
5. To release, tug the bight to unravel the knot instantly.

Pro Tip: Keep the bight long enough for easy pulling during release.

Inspect the string for wear or damage before tying.

Ensure the knot is snug and the bag is stable before relying on it.

Practice tying and releasing in low-risk settings first.
