+Burr

+Burr (Plus Burr) is a six-piece burr in an unconventional shape designed by Stephan Baumegger in 2015. The name derives from the negative space on each assembled face which resembles the addition symbol. With a level 8.1.2 disassembly is not trivial, but not overly challenging. I recommend disassembling and scrambling the pieces for a great assembly puzzle.

We have made two variants for this release, one with light white oak and rich walnut, and another with bright ash and intricate zebrawood. The wood pairings give each puzzle a visually pleasing contrast, with the large, chamfered pieces being easy to handle and providing very smooth movements.

65 copies are available for this release, each signed and dated. +Burr ships in an assembled configuration.
