In the maker's words

RELEASED: 3.8.2009 PRODUCED: 50 Copies DESIGNER: Goh Pit Khiam CRAFTSMAN: Eric Fuller MATERIAL: Cast Acrylic / Nylon / Stainless Steel COMMENTS: This excellent take-apart puzzle is the follow up to Goh Pit Khiam's 2004 "Key Puzzle" design. The original Key Puzzle used a binary locking mechanism. Tern Key ups the ante with a trinary implementation, yielding a hefty 134 move solution with four locks! Precision cut from solid cast acrylic and painstakingly hand assembled, this puzzle has a nice weight/feel, and will not be confused with cheaper mass produced take apart items. The construction uses contrasting press fit dowel pins to align the internals, and the push pins are stainless so they do not corrode over time. SIZE: 4" x 6"" PRICE: $49 (SOLD OUT) This item is sold out and no longer available. Our Marketplace is the best source for discontinued work. We occasionally revisit discontinued designs at our sole discretion and do not accept requests or one-off commissions.

We recommend an occasional polishing with Renaissance Wax to keep wood puzzles in top condition.
