I personally have once had these Sputnik razor blades: https://www.ebay.com/p/Sputnik-100-Double-Edge-Razor-Blades-...
In addition to being dirt cheap, I also found the branding funny. Somehow I felt like I am buying something not very good in terms of quality, but which does work (somehow) anyway. There were also pack called Lada's in there. I definitely felt like the Sputnik ones were better than the Lada's though.
