A portable and disposable device is provided for processing harvested dermal tissue. The device includes a housing presenting a handle having a gripping surface and a cutting head attached to the handle. A cutting assembly is supported by the cutting head and includes a plurality of spaced cutting blades that are rotatable with respect to the housing. A receptacle is disposed downstream of the cutting assembly and receives the sliced tissue from the cutting blades. The device is thus operable to slice harvested tissue into strips, and further into fine particles, that can be used for transplantation onto a wound site.
