The market for expandables exists only because some hunters can'tor won'tget their bows tuned properly.Is there really any other reason to use something that, by its' naturehas amuchlarger possibility for failure? Fixed blades are always exposed.

Expandables have come a long way but they still have a far greater chance of failing than fixed blades no matter how well made they are. They also can give a hunter with a poorly tuned bow a false sense of security. An arrow that is not flying well can impact in such a way as to exagerate the loss of kinetic energy when the arrow hits.
