You can trim the edges of DE blades so they fit 1912s but watch out - it's a superboost!
It is a pretty razor but shaves mediocre for me.There is a brand new SE razor specifically designed to take half DE blades.
It is called the Yaqi Katana... check it outView attachment 1211209
Um . . . why would you want to?
Just buy a Shake Sharp would indeed be the best advice ever. Loaded with two blades of course.I might as well add to this old thread that there are SE razors that accommodate DE blades. In the history of safety razors a handful of SE razors such as Capital Golf and Shake Sharp used only DE razor blades. There is no need to modify or tamper these razors they work with DE blades only. I know that isn't what the OP was looking for but I thought I would pass this info anyway.
