What is a fan knife?

Fan knives, also known as balisong, are a type of folding knife that is characterised by its opening and closing mechanism using two handles that rotate around the blade. This design allows the blade to be completely concealed within the handles when closed, providing greater safety and portability. Fan knives originated in the Philippines and have traditionally been used as both work tools and self-defence weapons 

Origin of the butterfly knife

The history of the butterfly knife is shrouded in mystery, but most historians believe it originated in the Philippines, where it was used as a general-purpose tool and self-defence weapon. There are records of its existence as far back as the 18th century, and it is a traditional part of Philippine culture. On the other hand, some theories suggest that it may have originated in Europe, specifically in France, where similar knives have been in use since the 17th century. Regardless of its true origin, the balisong gained worldwide fame mainly thanks to the Philippines, where it became part of the country's cultural and martial identity.

How to use the fan knife

Using a fan knife requires practice and skill, as the opening and closing mechanism can be complex for beginners. To open a fan knife, hold one of the handles and twist it outwards, allowing the blade to unfold. This movement can be done quickly and smoothly with practice, which has led to the creation of various manipulation techniques and tricks. It is important to remember that, although fan blades can be fun to use, caution should always be exercised and practised in a safe environment to avoid accidents 

To begin with, it is advisable to use a training knife, which does not have a sharp blade, to familiarise yourself with the basic movements without the risk of cutting yourself.
