Abstract: A light emitting fire knife device includes a blade structure, a first planar light emitting component, a second planar light emitting component, a handle structure, and a first cylindrical light emitting component. The blade structure includes a first distal end and a second distal end opposite the first distal end. The first planar light emitting component is disposed on a first planar surface of the blade structure and the second planar light emitting component is disposed on a second planar surface of the blade structure, where the second planar surface is opposite the first planar surface. The handle structure includes a third distal end and a fourth distal end opposite the third distal end, where the third distal end is configured to removably secure to the second distal end of the blade structure. The first cylindrical light emitting component is secured around the handle structure proximate the fourth distal end of the handle structure.
