I have used a Safety Razor in the past and generally shave with one of the disposables. I still have my Grandfather Kriss Kross SR stop that would "re-edge" the blades for a little more use. I can't remember where the safety razor went, maybe out to Goodwill. I use a Shick disposable until it simply doesn't like to "save" well anymore.
Looking in eBay I see many different straight razors, and stops. Some new, some old (vintage). I remember seeing my Uncle and his Uncle shaving with a straight razor growing up on the farm in NW rural Nebraska. I have, and still use, the crock shaving mug he had and the old badger hair brush that he used. I'm 57 and he was using it before I came along, so it is still holding up pretty well. I've only started using the saving cup/brush in the last couple of years, so it has sat in the closet kind of quiet all this time.
I see straight razors made in China, and other places. Some priced pretty cheap, and others not so. I don't know if carbon steel makes for a better razor for shaving, or if Stainless Steel is considered good. I hope to learn. When I used to get a hair cut in Oshkosh, NE when I was in High School, the barber was kind of old school and would later up my neck and around my ears and use a straight razor on me. Then he got the straight razor with disposable blades. I was kind of glad, because a lot of times he did some pulling with his shaving.
Don't know anything about Dovo, Kreigar or the others. So I look at them in eBay with ignorance. I sharpen my knives to cut hair, so I think I can manage getting a razor sharp enough to shave, as long as the quality is there.
