Lock Nut (STC-105)

designed by Stewart Coffin
crafted by Eric Fuller (2005)

• condition: as new
• description: Stewart Coffin's design #105, originally created for the IPP 16 puzzle exchange, combines a deceptively simple appearance with a clever interlocking mechanism. Crafted from Cocobolo, it is an exceptionally rare Eric Fuller puzzle, with only 14 copies completed after the complex angled cuts proved far more difficult to manufacture than expected.
