One of my clients found this at a garage sale. Traded it for a pocket knife!! Before and after pics. Now just need to do the research for a blade that fits it.
The head is too shallow for a despined GEM. You can use an injector blade, but you'll have to come up with a spacer of some sort to keep it from sliding back into the razor head. I cut a piece out of an old credit card for mine. The shave was tolerable, but just barely.
