Every piece of the puzzle is precisely cut and very well madeyou cannot find its equal anywhere else. The diversity in wood makes each puzzle a unique masterpiece. Kevin Sadler writes about it: "Jakub and Jaroslav don't make very many burr puzzles these days but when they do any burr fans should sit up and pay attention &ndashthey only choose the best of the best of them and this marvelous design by Stephan Baumegger is fantastic. The wood choice and finish with all the bevelling is the mark of fabulous attention to detail. Inside is a shape that gives the puzzle its' name. The movements are smooth and there is minimal catching of the pieces as they slide. I was really very pleased that Jakub had sent this to me several weeks ago as it took me several weeks to wend my way through the maze of moves. The puzzle does not have a stupendously high level (26.2.1.1.11.2) but is a wonderful challenge with lots of exploration. The blind ends are frequent but not too long and so not too frustrating. Inside is the bulldozer which is one of the most beautiful pieces of wood work I have seen from them.&rdquoDesigned by: Stephen BaumeggerMaterial: WengeCherryBubingoAmerican WalnutAmerican Walnut2022-08-21 08:37:59.570instock
