Dual Tetrahedron 03

The four pieces of this puzzle are painstakingly handcrafted from ash, rosewood, and plum.  (Each puzzle is unique, so coloring may vary.)

Designer Vaclav Obsivac has used contrasting colored woods to form a beautiful symmetrical shape with this puzzle. Your job is to find where the four pieces join so you can take it apart. Quite a challenge... Perhaps the biggest of all being able to put it back together!
