Holey 6 Board Burr II

Junichi Yananose was the first puzzle designer to create a board burr way back in 1990.

This Holey 6 Board Burr II is one of the designs that came out of the analysis of another set of burrs that Junichi did in 2009.  Unique solution.  2483 false assemblies.  And for this set he added a completely new feature which is the holes in the end of the burr.
The puzzle is sold dissembled and we’re rating it 10/10 to put together (goes without saying this is without using BurrTools or another computer program to help!)
Don’t despair. There is a very detailed step by step solution drawn by the designer to help you assemble the puzzle when you totally give up.
