The tool operates on the principle of mechanical feedback analysis. When tension is applied, the pins bind at the shear line between the plug and the housing, setting the stage for precise measurement.

• High-quality Lishi tools are precision-machined from hardened tool steel with extremely precise etching. Inferior counterfeits often use softer metals and imprecise markings, leading to poor performance, making genuine tools a necessary professional investment.

• By simply inserting the tool and running the lever, a user can quickly count the number of active pin chambers. Even when not decoding, the integrated tensioner can serve as an exceptionally well-fitted tension wrench for traditional picking on its designated keyway.

• The key codes you derive are sensitive security information. Securely record them for your job ticket and maintain their confidentiality. Never discard such information in public view.
