Gregory took one look at the traditional 6-piece burr style and decided to design a 6-piece burr that would torment and screw with the minds of all prospective burr solvers. He cut out triangular notches, added triangular cuts, and introduced a wild coordinate-motion moves integral to taking this burr apart and back together.
For such a remarkable idea, it's oddly hard to find anyone who is willing to make copies of this series! Eric noted that it'd be a nightmare to make and turned it down. But Gregory was clever and handed him a copy to try and after that, Eric had to make this puzzle. Tom Burns also loved this puzzle after trying it himself and decided to make print copies of it and that's how I got my grubby hands on these 2 burrs after longingly looking at every picture of these remarkable burr. Sadly enough, I believe Tom only ever made and sold the first 3 burrs in the series before dropping the project. I still appreciate his part in letting me get to enjoy playing with these burrs and dislike him for my lost hair when I was tearing at my head out of frustration on how to take the burr sticks apart and them back together!
Note that the family picture of 4 NOS Burrs are just me showing a group photo of my collected NOS Burrs. Only the 2 prints are being sold in this auction. The 2 wooden NOS Burrs are in separate auctions from this one.
