The Complete Handbook of Orchestral String Instrument Bow Cases

Chapter 1: Understanding Orchestral String Instrument Bow Cases

A bow case for an orchestral string instrument is not a padded bag. It is a rigid, engineered enclosure designed to hold a precision tool under the specific conditions of travel, storage, and changing climate. The bow is a slender wooden shaft under tension, tipped with a fragile piece of material, and fitted with a delicate mechanism at its base. Unlike the instrument itself, the bow is often carried in a separate case, tucked into a rucksack, wedged under an arm, or slotted into a suitcase. In all these scenarios, it is exposed to forces that can bend, break, or distort it. The bow case exists to prevent that, and the difference between a good one and a poor one is often the difference between a bow that lasts decades and one that fails within a season.

Consider the physical reality of a violin bow. The stick is carved from a single piece of wood, typically pernambuco or brazilwood in older instruments, or carbon fiber in modern ones. It is planed down so that it flexes inward toward the hair under playing tension. When the hair is slack, as it should be for storage, the stick returns to its natural straightness. But this springiness is not unlimited. A bow that is subjected to strong lateral bending, such as when a case is squeezed into an overhead compartment and the bow is pressed against the case wall, can develop a permanent warp. A
