Martin's Menace Large is a handcrafted 4-piece wooden brain teaser, Stewart Coffin Design #217, originally called "Four Fit." Martin Gardner, the Father of Recreational Math, spent a week trying to solve it and renamed it Martin's Menace after calling it "the finest dissection puzzle of all time."

Fit four pieces into the frame. Few solve it without help. The pieces are precision laser-cut from durable hardwoods. Handcrafted by Creative Crafthouse with Stewart Coffin's permission.

• Dimensions: 6 inches square.
