First, double knot (simple and practical, easy to beat and disassemble)
1, first wrap the rope around the object twice.
2. Then pass the rope end through the second loop and tighten it hard.
3, finally make a half knot.
(Attached) Half-knot play: first cross the rope end with the rope, and then tighten the passing rope end.
Second, the anti-figure knot (anti-drop, even if the two ends are pulled tightly, it can still be easily untied)
1. Tie a splayed knot in the middle of the rope, first pass through the rope head, then the rope head bypasses the main rope, and then tighten it after passing through the rope loop.
2. Thread the rope head through the end of the rope from the opposite direction along the knot.
3. Thread the rope end through the first knot and wrap it back under the knot.
4. In the process of rewinding, thread the rope head through the lower rope loop.
5. Adjust and tighten.
(Attached) Figure-of-Eight Knot Playing Method: First, cross the rope ends, then bypass the main rope, and finally pull the rope ends through the rope loop, and you're done.
