This interlocking Burr wooden Puzzle consists of twelve identical notched rods.
Once the pieces are disassembled you will see why it is called Devil's Friend. It is a very difficult puzzle requiring advanced burr puzzle solving methods. The puzzle was created in 1890 by the Austrian-German William Altekruse who even registered a US Patent (#430502).
This puzzle is not quite symmetrical visually because the asymmetrical notches arrangement reveal themselves. Disassemble and reassemble the wooden pieces into a cube and various 3D shapes.
Dimension Large = 8x8x8 cm
Difficulty Level: 3 of 5.
