A type of lockback folding knife originally from Germany. These are very popular in much of the Africa and much of the Caribbean. Ratchet Knives are often associated with gangs and criminal activity. In Jamaica they were closely linked with "Rude Boy" street culture.
Ratchet Knives are named for the ratcheted blade lock mechanism.

The ratcheted blade lock mechanism keeps the blade from snapping shut on the user's hand even when only partially opened. The ratchet knife is usually unlocked by using a pull ring on the back rather than the more common push buttons or levers of most lock blades.
Both of these features make it less likely for the knife to snap shut across the user's fingers during a struggle.

However the key to the popularity of these knives is mostly due to their extremely low price, wide availability and intimidating ratchet sound on opening.
The most famous brand of ratchet knife is the Okapi. Originally made in Germany for export to German territories in Africa the production of Okapi knives moved to South Africa during the 1980's where it is still a very popular all around knife, especially with local criminals.
The Okapi was also the favored ratchet of Jamaican rude boys who often referred to them as "Three Star Ratchets" due to the three stars inlaid on the handles of many Okapi brand ratchet knives.

1. Someone, usually female, that acts ghetto, loud, obnoxious, trashy, very ugly, and can be promiscuous.

2. This term may be used in a way that shows jealousy. For example, a normal person that doesn't act ghetto or trashy or ratchet may be called those things because they act normal and better.

Either way, a ratchet person tries to start unnecessary drama for the world to know.
