“I have never actually seen one of the Rosebud puzzles in the flesh/wood before! I have seen photos and blog posts but people seldom bring them out to let others play with them because it’s such a difficult challenge to reassemble it. This amazing design by Stewart Coffin is one that sets the masters of their craft apart from a mere journeyman woodworker. Rosebud is a coordinate motion puzzle that is one of the most challenging to manufacture as the tolerances have to be accurate to fractions of a millimetre to allow the pieces to slide on each other and for it to close up into the rosebud form without showing any gaps.
I have never owned one of these because the level of craftsmanship makes them very rare and very expensive. Of course, Jakub and Jaroslav have managed to make a superb version that is absolutely perfect with the wood choices being evocative of a rose and the precision being simply spot on. Finding the proper pressure points to cause it to slide apart is difficult but then you need to control it so that it doesn’t fly apart. You need to catch it in the expanding splendour that reveals the Rosebud come into bloom before the petals fall off and it dies like a fading flower.
Reassembly into the true Rosebud form is the real challenge. It is so difficult to assemble that most puzzlers need a jig (or 4 more hands) to hold the pieces properly for the assembly. This puzzle is a masterpiece and should be on every serious collector’s shelf.”
