Adjustable Horsehair Bracelets: How the Sliding Knot Closure Works
The sliding knot closure on a real horse hair bracelet operates on simple mechanical principles. A loop of braided horsehair passes through or around a knotted section, and the knot's position on the loop determines the bracelet's effective diameter. Pulling the tails of the knot tightens the loop. Pushing the knot toward the loop loosens it. No tools required, and the closure is fully reversible.
This type of closure works well with horsehair because the fiber has enough grip to hold the knot's position during wear without being so rough that it damages the braid over time. An adjustable genuine horse hair bracelet sized correctly should hold position on the wrist without requiring re-adjustment throughout the day.
