Unlike Gillette, safety razors do not use proprietary systems for their blades. The consequence is you can use any double edge blade and you can have fun finding the double edge blades that best matches your razor and beard. Shameless plug: years ago with my brother I made this small site (https://www.razorbladesclub.com) that I presented on "Show HN" exactly to allow people to buy samplers of blades and try them out. It didn't get much attention then but years later the site is still alive and hopefully it still serves people well :)
