Question: 1 / 435

What is the name of the bitted edge of a single bitted key?

Top of Blade

The bitted edge of a single bitted key is referred to as the "Top of Blade." This terminology stems from the design of the key, where the bitting, or the cuts made into the key, exists along one edge of the key blade. These cuts correspond to the pins in the lock, allowing the key to engage the inside mechanism properly and unlock the door.

Understanding the anatomy of a key is essential for locksmithing, as it aids in the creation, duplication, and function of keys within various locking systems. While the key blade is the entire body of the key and includes both the bitted edge and the tip, the specific name for the bitted edge is crucial for clarity in discussions about locksmithing and key-making techniques.
