The present invention is directed to a bone marrow biopsy needle including an outer cannula having a proximal end, a distal end, a hollow section therebetween and a handle portion associated with the proximal end, and an inner rod having a proximal end, a distal end and a handle cap. The handle portion further includes a grip enhancement member which is formed from a material distinct from at least a portion of the handle portion, such as rubber. The grip enhancement member may take the form of insert members which fit into cavities in the handle portion of the outer cannula. The grip enhancement member not only enhances the gripping surface of the bone marrow biopsy needle, but also provides cushioning for a user and adds weight to the handle portion to facilitate weight distribution throughout the outer cannula handle.
