The thing about razor blades is they don’t last forever. You need them to be nice and sharp to get a clean cut, and that means replacing them every so often. I’ve looked high and low and it appears that there aren’t as many companies producing the actual blades as the razors themselves. The options I was able to find are listed below.
Battle Brothers Shaving Co
US-made double edge safety razor blades that are universally designed to fit all standard double edge safety razors, making them a versatile choice for your grooming kit. Be aware that the company does sell some blades that are cheaper that are produced overseas. From what I have read, I understand this is old stock and now they are manufacturing their razor blades in the USA.
Personna
The number one mentioned brand for razor blades made in the USA is without a doubt Personna. They’ve been around for a long time and are a popular solution.
Western Razor Co
Premium stainless-steel blades that are made with 3-faced edges to retain sharpness and ensure a precise cut, providing the perfect compromise between mild and aggressive. They are coated and oiled for a clean, smooth shave, and very durable, lasting 5-7 shaves each.
Supply
All other single-blade razors force you to unwrap and load thin, sharp blades by hand. That’s why Supply designed a custom-built injector mechanism which keeps your fingers safe, and enables lightning-fast blade changes. It comes loaded with 8 USA-made blades.
