Sher-Lock - A Notched Trifecta

Sher-Lock - A Notched Trifecta is a very exciting new design by IPP award winning designer Girish Sharma. This design is a part of his Sher-Lock series of padlock-shaped interlocking puzzles. The name alludes to the three different configurations of the key-shaped burr piece within the solved puzzle. We hope to offer more designs from the series in the future, and we are proud to offer this unique and challenging puzzle. 

Each assembly has not only a unique solution but a distinct arrangement of the pieces. The design takes advantage of subdivided voxels and angled half-unit pieces to achieve this impressive feat. An intimidating level 19, 24 & 25 solution for each configuration further adds to the complexity.

Fit of the puzzle is precise, and care must be taken to keep the points of the angled pieces from chipping. The quartersawn cherry cage features precision mitered joinery and the pieces are made from a dense board of purpleheart to give a satisfying operation, solid feel, and a nice color contrast. The puzzle is slightly larger in scale than our normal burr size to accommodate the triangular-shaped stock.

Sher-Lock - A Notched Trifecta ships in an assembled configuration. Approximately 75 copies were made for this release, each signed and dated.

Our work is handcrafted to very precise tolerances and must be kept within the range of 40-60% relative humidity at all times. Failure to do so may cause inoperability or permanent damage.

Please read the Caring for Wood Puzzles guide to ensure proper fit and operation. We recommend an occasional polishing with Renaissance Wax to keep wood puzzles in top condition.
