Question: 1 / 435

What is referred to as the 'Bit' in the context of keys?

The part of the key which serves as the blade

The portion of a key that is cut

In the context of keys, the term 'Bit' specifically refers to the portion of a key that is cut to fit the pins of a lock. This section of the key is intricately designed with grooves and notches, which correspond to the internal mechanisms of a lock. When the correct key, with its uniquely cut bit, is inserted into the lock, it aligns with the tumblers inside, allowing the lock to turn and open.

Understanding this is crucial for locksmithing, as it emphasizes the importance of precision in the cutting process and how the bit interacts with the lock's components. The blade of a key, the grip or handle, and the uncut part do not play the same functional role in engaging with a lock mechanism as the bit does.
