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.
Round Trip is a mean one that bumps up the difficulty past the first 2 burrs in the series and I kept sliding pieces around and around before finally tugging all of them apart. But I needed a video guide on how to reassemble them all back together! NOS Burrs are brutal and not for the faint of the heart.
Note that the family picture of 4 NOS Burrs are just me showing a group photo of my collected NOS Burrs. Only one burr, the padauk Round Trip, is being sold in this auction. The other 3 NOS Burrs are in separate auctions from this one.
