Hard Nut To Crack

Goal: disentangle wooden ring. The result you can see on the photo below.

This puzzle consist of three detail: nut with rope loop, rope ring and wooden ring.

For experienced puzzlers this question is not very difficult, but if you are only beginner it may be not easy. I estimate level of difficulties as 3 of 5 possible.

I think, at least exist two types of disentanglement puzzles: first – for hands, second – for eyes. This puzzle for eyes, it couldn’t be solved just twisting by hands. It requires attention and concentration.
