I have used a Schick injector razor about 57 years now. Works for me. I like it because single blade, is light so packs well for travel and the injector blades come in a small package also. So unpopular can hardly find them in stores any more but Amazon has them. I have tried the cheap off brand blades but went back to the genuine Schick. Seems like the quality of the cheap blades was not consistent. One batch would be ok (not especially great life) and the next dull. Have never had any problems with the genuine Schick blades.

I have two of the blade handles. One from way back in high school, still the original handle. And another one I use for travel in my over night bag that I bought probably 20 years later.
