1. Use a needle to assist in unraveling
First, lay the necklace flat on the table, then gently poke a needle into the knot, slowly move it on the table, and slowly pull the necklace out. One knot will be untied. The needle tip is relatively sharp, so be careful when using a needle to remove the necklace buckle to avoid scratching the tabletop and fingers.
2. Lubricating oil auxiliary
You can drop a drop of baby oil or olive oil on the knot and gently rub the oil into the knot. The oil can soften the metal and make the necklace smoother. After lubricating the necklace, it is easier to undo.
3. Flat unfolding method
Place the necklace flat on a flat and hard surface, and unfold it as much as possible when placing it. Separate it as much as possible. Unfolding the arrangement is beneficial for you to see clearly where the knot is, so that you can handle the necklace knot in a targeted manner.
