Alfons specialises in fabulous burr designs. They are all very beautiful and many of them are incredibly tough. This is definitely the case here – the two burrs that have been designed and created for this release are stunning and extremely difficult puzzles. I think that the disassembly is hard enough – the reassembly will be absolutely impossible without Burrtools. The Lange Vinger is yet another of Alfons’ incredible framed 6 piece burrs. This burr is made from Wenge with Lime pieces. It has an odd rotational symmetry to it which really throws my ability to follow moves. The frame pieces have been made so that each one of the main burr sticks is blocked at one end making the disassembly much more complex
