What is flexible blade

A flexible blade refers to a type of blade that has some degree of bend or flexibility. This term is commonly used in reference to knives, swords, or other cutting implements that have blades that can bend or flex slightly without breaking. Flexible blades are designed for specific purposes such as for tasks that require more control or for swordsmanship styles that benefit from the ability to bend or flex the blade. Flexible blades are different from rigid or stiff blades which are designed to maintain their shape and straightness under heavy stress or impact.
