So I just picked up a Penn safety razor on a hunch. Well my theory was correct they can in fact securely hold injector blades. I haven't tried a shave yet. The razor can hold the blade with both a more aggressive exposure like in the picture or a much more mild exposure. You just slide the injector blade in and tighten the handle and the handle screw locks it in just like the original blades.
