“Over the 15 years of my blog, I have reviewed several versions of the Convolution puzzle by the amazing Stewart Coffin. This incredible interlocking design is not solvable by Burrtools due to the requirement for a rotational move with one of the pieces (does that make it a TIC?). I have a version from Brian Menold and a fabulous spherical version from Pelikan.
 
I personally would say that a Convolution (as well as its associated cousins, Involute and Involution) should be part of every serious puzzler’s collection. All 3 are essential. If you don’t have this, then you owe it to yourself to buy a copy. The Pelikan team have done a wonderful job creating this out of multiple different beautifully vibrant woods and the fit is just perfect! If you are feeling clever then get someone else to disassemble it for you and try and assemble it from scratch. It is only possible if the pieces are added in exactly the correct sequence. Great fun!”
