A butterfly knife is a folding pocket knife that originated in the Philippines and is sometimes referred to as the Batangas knife. It is quite different from most pocket knives, as it has two handles that fold and the blade rests between them. Also, it can make a “clicking” type noise when this is done quickly, and you are able to, not only do it quickly, but also with one hand.
The Filipino name actually has two separate meanings, the first one means a folding knife with two handles which wrap around the tang, while the second one is to be made of broken horn. There are old butterfly knives for sale worth thousands of dollars due to the ivory inlays of them.
Some of the other names butterfly knives are known by are switchblade, gravity, fan, and it can be brought to bear quickly. Along with its use as a tool, it was also used as a weapon, and today that has created problems with being able to own one in the country of your choosing. It has been outlawed in several Western Countries because of its potential use as a weapon, intimidating nature and rapid deployment. The following is a sampling of the restrictions placed on them: Australia is generally classified as being prohibited; Canada is not specified by name, however it is considered in the courts to fall under the gravity knife rules, therefore it is illegal unless it has been grandfathered in; the UK has considered it an offensive weapon since 1989, however if it is over 100 years old, it may be considered an antique; and the USA determines by category per state.
It is a true form of art to watch someone use it in exhibition. The clicking sound reminds me of watching the “River Dance.”
