Why Butterfly Knives are Illegal In Some States

Butterfly knives are illegal in some states for several reasons. First, they are often associated with violent crime. Many movies depict criminals using butterfly knives. Many knife enthusiasts feel that this is not a legitimate reason to ban these knives, as there is no data that shows criminals are more likely to use butterfly knives than other knives.

The other reason that butterfly knives are banned is the speed with which they can be deployed. Deploying a butterfly knife quickly requires a great deal of practice, but it can be done much faster than opening a standard folding knife. This has led some states and local jurisdictions to group butterfly knives with switchblades. Other jurisdictions ban butterfly knives together with other knives in the category of "gravity knives." There is some controversy about whether the speed with which butterfly knives can be deployed actually makes them a more effective weapon for the average criminal. Most fatal knife attacks have involved hunting knives or combat knives, not butterfly knives.
