In a pin cylinder, what is the term for the location where tumbler surfaces align to allow rotation?

  1. Keyway

  2. Shear line

  3. Lock face

  4. Cylinder chamber

The correct answer is: Shear line

The term that refers to the location where tumbler surfaces align to allow rotation in a pin cylinder is the shear line. When the correct key is inserted into the lock, it raises the pins to precisely the right height, aligning them at the shear line. This alignment is crucial because only when the pins are correctly positioned can the cylinder rotate freely, granting access. Understanding the mechanics of the shear line is essential for locksmiths, as it directly affects their ability to manipulate locks effectively and understand how these systems are designed for security.
