Using diagonally oriented wooden pieces has been a distinct feature of wooden interlocking puzzles made in Finland for over 100 years. The National Museum in Helsinki exhibits a diagonal burr made around 1910 but it is known that as early as 1888 Chandler patented a 13 piece diagonal burr. Diagonal burrs are said to have been made by lumberjacks in camp for over 60 years, are known to have been made by Finnish soldiers in the trenches in WWII and as recently as 1985 were being made by Finnish puzzle designer Matti Linkola, but these days are not commonly made.
We expect this 25 piece version to be quite a handful.
