VIP Woodchuck Puzzle ***

This high quality 3-D-puzzle is made of padouk, maple and black walnut. So it is not only a tricky puzzle but also a nice decoration. It consists of 24 pieces and is packed into a very nice carton box with magnetic closure.
Here is the historical explanation for this woodchuck puzzle:
The chuck puzzle system was invented and patented by Edward Nelson in 1897. Improved by Ron Cook of the UK company Paradox Eng. Ltd. AKA Pentangle Puzzles, during the 1980s and 90s. They produced a series of chucks in which a given number of simple bridge-like pieces and one or more key pieces with an extra notch, could be built into a variety of self-sustaining three-dimensional shapes. For creating bigger chuck puzzles, at that time named Papachuck (54pcs), Grandpapachuck (96pcs) and Great-Grandpapachuck (150pcs) by Cook, one would need to add longer pieces. This idea can also be used to create asymmetric shapes, assembled exactly according to the same principle as this Woodchuck puzzle. The feature is unique to chuck puzzles.
