Teak

6.75"w x 6.75"d x 6"h

I truncated a cube out of a solid peace of teak to make this Icosahedron.  It has 20 equilateral triangular faces and 12 vertices - the exact opposite of the Dodecahedron.

Hand carved

As with most my work, i have intentionally left the tool marks to show the hand of the process
