2-In-1 (Stainless Steel) by Oskar van Deventer made by Cubic Dissection

As shown by the previous releases we crafted from solid wood in its intended rectilinear form, 2-in-1 is one of our favorite burr puzzles. Eric recently had the idea to try the same assembly in precision milled round metal. The result is profound, a reinvention that adds significant difficulty and results in a beautiful, hefty metal sculpture.

This twelve-piece serially interlocking burr has a unique solution and multiple challenges. Merely deciphering the proper location and order of the pieces is the first challenge. Manipulating the parts to create the final assembly is its own trial. It requires dexterity and inventiveness (we take pity by including small elastic bands to aid in the process).

2-in-1 can be difficult and frustrating, but the result is worth the effort once solved. The solid stainless steel pieces interlock with absolute precision, each measurement accurate to within 0.05 mm. The final weight of over 1 lb (.5kg) is a testament to the materials' quality. In sum, 2-in-1 is a beautiful puzzle you won't regret experiencing.
