This puzzle is part of the series "Sharp Edges". All modifications of this series are made by truncating an 3x3x3 on its edges. These truncations are not symmetrically as in the octagon regularly. One dimension of the cut goes deeper than the other. The best example to view the cutting depths is "Idiots Windmill" which is in the museum too.
The technical signature (18051D2E28060) indicates where to cut the original cube.
Some members of this series are made solely by truncating. Others receive additional extensions to "delete" some of the remaining faces.

The shape of this puzzle combines the cuts of the flat octahedron and the sharp octahedron made by the same inventor.
