An Ultimate Skewb with 2 sides "deleted".
Aka ExtendedUltimateSkewb F8000000000000000000000000001F
A straightforward extension of an Ultimate Skewb.
This mod is a member of the Extended-Ultimate-Skewb series. In this case two sets of 4 extensions each are glued on opposite faces of the Ultimate Skewb. These are the same extensions as used for the small stellated dodecahedron skewb. The result is a solid with 10 identical faces. Although this mod could be made with plastic sheets the extensions are massive in this case. It weighs 252 grams.
This puzzle is part of the series "Extended Ultimate Skewb". All modifications of this series are made by "deleting" some faces of the original puzzle. This is achieved by gluing on some extensions.
The technical signature (F8000000000000000000000000001F) indicates on which sides extensions were glued on. Some additional extensions might be placed between the first set too. Whether this is done or not is decided without general rule.
If you're looking to buy, eBay is the one place you can find almost anything... if you're willing to wait for it, then pay the price!
