Separate the two halves of the cross. A unique and intriguing as when he first made it more than 30 years ago by Wil Strijbos. A brainteaser of high quality and extremely difficult to solve! This puzzle is an ongoing adaptation of the inventor, who created his first wooden padlock in 1979. Unlike the Sweta Cross, there is no marble in it and no magnets. The solution lies precisely in the elastic strength of the aluminum pieces. A real challenge for puzzle lovers!
