keen kutter safety razor lot

Picked up a box of grooming gear at a estate auction today. From what i have learned, they were all made by a company called Christy out of Fremont Ohio. There's one with a long handle called the hoe, the shorter version with what was marketed with a massage bar (instead of a open comb) and then the Keen Kutter version with the red cell handle (in it's original box with instructions).
There's a extra handle that i believe was used to strop the proprietary blades though i'm not sure how it works or if it's all there. If anyone has any knowledge of it let us know. i understand they can be used with a injector style blade so maybe i'll hang on to them for a while and give it a try.
