Knotty 6 - Yavuz Demirhan (2013) by Pelikan



This puzzle is a bit of a throwback to a time when high level board burrs weren’t so prevalent, (Torture by Frans de Vreugd being the exception).  This design won’t have you scrambling for a burrtools file to reassemble as it only requires a couple of moves but still a neat puzzle to play with.  Pelikan weren’t set up at their current shop, however the craftsmanship is still quite evident and this copy is made from Padauk, Maple and Wenge.


Gabriel blogged about this puzzle back in 2014, here’s an excerpt:


“Knotty 6 is designed by the prolific Yavuz from Turkey, and manufactured by Pelikan in the Czech Republic. The puzzle is made from very high quality materials and a lot of care went into producing each copy. The wood is dried to 8% moisture, and a lot of varied species of wood are used to have an extensive diversity of colors and textures in their designs.


The puzzle consists of six identical P-shaped pieces, or congruent, and they interlock to form a tight knot, which at first seems impossible to undo. However, the two holes inside allow for the pieces to move in a certain way so it's possible to remove one piece at a time. I found that there are multiple solutions to remove the first piece, as seen in the pictures below, which indicate that any of the three colored pieces can be the first, although the solution is identical in all three occasions. The pieces move by sliding them one unit at a time. You need two moves to remove the first piece and another two to remove the second. No rotations needed.”
