Partly it's the visual appeal of the razor if I'm honest. I can understand the reluctance to follow the Blackland solution and the reliance on a flat thread. Yes, the head is smaller but only without a blade in your razor concept. It seems to me the issue is the threading for the handle for modern GEM designs. I can't tell exactly how your design fits together but I'd like to see a new GEM with the handle attached below the baseplate like a vintage razor.
The ER streamline threads the handle under the baseplate for example. This would save space and allow you to have a small head size and still enclose the blade. The baseplate is barely wider than the blade itself on the streamline. The threading on the cap/hole in the baseplate is what makes the Wolfman head so large. Maybe a 2 piece design could help? Either spring loaded or the cap could slide across to lock in place. I get that both the Sabre and Wolfman tighten down the threaded handle to hold the head and blade together but I don't buy that as the only solution.
It has nothing to do with safety - of course the back of the blade is perfectly safe.
Or maybe I just need to design my own modern GEM razor...
