Great point brought up about blade rigidity, I really like injector style razors for this reason I just found the blades to be a bit costly in relation to the number of shaves I got from them so I went back to DEs
I havent used an injector type razor, but I do understand them to be very rigid in design.
There are quite a few rigid design DE razors. This one as a very inexpensive option for a modern razor.
