To untangle knotted chains, you can start by gently pulling on the ends of the chains to see if the knot begins to loosen. If that doesn't work, you can try using a small tool like a needle or a toothpick to carefully work at the knot and separate the chains.

Patience and a steady hand are key to successfully untangling knotted chains without causing any damage. **
