What defines a progression that uses a one increment difference between bittings of a given position?

1. Single Step Progression

2. Sequential Bitting

3. Incremental Progression

4. Standard Step Format

The correct answer is: Single Step Progression

In locksmithing, a progression refers to a method of creating key bittings that follow a specific pattern or system. When discussing a progression that specifically uses a one increment difference between bittings of a given position, the term "Single Step Progression" accurately describes this concept. A Single Step Progression involves changing the bitting of each pin (or position) by a single increment from one key to the next. This method allows locksmiths to systematically generate keys by incrementally adjusting the depth of each pin, which is particularly useful for creating keys that fit a specific lock without requiring extensive trial and error. The term captures the essence of changing each pin position in a precise, measured way, which contrasts with other types of progressions that may use larger jumps or varying increments. This method is straightforward and is often employed in locksmithing to simplify key duplication or creation processes. The other options suggest different methods or concepts that do not specifically adhere to the one increment difference characteristic central to Single Step Progression.
