Ratcheting knives are a type of folding knife characterized by having a locking mechanism known as a 'ratchet'. This mechanism uses a toothed wheel and a spring to lock the blade in its open position, thus providing greater security and stability during use.
The ratcheting knife is known for its sturdiness and durability. In addition to the ratcheting mechanism, they usually feature a stainless steel blade that folds into the handle when not in use.
Ratcheting knives are popular because they were used by Spanish bandits of the 18th-14th centuries.
