What does "Cut Root Shape" indicate in locksmithing?

The overall length of a key

The finish of the key's surface

The shape of the bottom of a key cut

In locksmithing, "Cut Root Shape" refers specifically to the shape of the bottom of a key cut. This aspect is crucial because it determines how the key interacts with the pin tumblers inside the lock cylinder. The profile and shape of the cut at the root can affect the alignment and movement of the key when inserted into the lock. A well-defined root shape ensures that the key can properly engage with the locking mechanism, allowing for smooth insertion and operation.

Understanding this concept is important for key making and duplication, as any irregularities in the cut root shape may lead to key malfunction or failure to properly unlock the door. Thus, a locksmith must pay attention to the specifics of this shape to maintain functionality and security in the locking systems they work with.
