The cylinder
Bullet-type blade cylinder, not a pin tumbler
Most padlocks at this price use a pin-tumbler cylinder: a row of spring pins that a pick, a bump key or a sheet of tin foil can push into line. Our locks use a bullet-type blade cylinder instead. The cylindrical key sets a stack of blades, and the tools made for pin tumblers do not work on it the same way — it takes far more to open.
- Designed against master keys
- Against tin-foil openers
- Against picking tools and single-hook Z tools
- Cylindrical key, hard to copy at a key cutter
