Just bought a Ever-Ready 1912 from the 1930s and a pack of GEM single edge blades (for shaving, not scraping paint). The razor is in great shape. After loading the razor with a GEM blade (as per several You Tube videos), I started shaving with it. As per the videos, the best angle for shaving is far different than a DE razor or a Schick injector. The first shave was good. The razor very efficiently shaved my cheeks and did a decent job on the neck. Don't have to shave the lip and chin because I have a goatee. No nicks. This morning I shaved for the third time with the GEM blade.. Still no nicks, but a pretty rough shave with some irritation on the neck for the first time. Shaving the neck is harder than shaving the cheeks. I'm not prone to irritation. My prior shaves were with a Schick G-1, which shaved wonderfully. Is it time to replace the blade after 3 shaves? Is my technique (holding the head flat to my face) not good? Neat razor, but I will retire it to the collection box if things don't improve with the 4th shave.
