Designer: Ken Irvine
Puzzle type/category: Interlocking
Difficulty level: 5.1.1
Material: Various wood species, brass rods

I discovered this puzzle in Brian Menold's book, WOODEN PUZZLES. This is a different version than the one you'll find on Brian's site, WoodWondersOnline.com, which requires rotations, whereas this original version does not. To differentiate the two, you'll notice the later version has a half-cube.

Material: Walnut, and a couple mystery species! Brass rods.

Material: Black Limba, brass rods
