The sharpest blade is not necessarily the best. The "perfect" blade, should such a thing exist, depends on your razor, beard and technique.
Shameless plug: should you start the search for the perfect blade, at https://www.razorbladesclub.com/ you'll find the widest selection of double edge razor blades worldwide.
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 :)
Author here. I and my brother have been working on this for the past couple of months and would love to get some feedback on it. It's a small service for the wet-shaving community aiming at offering a variety of double edge blades (even in quantities as low as one blade) as a one-off purchase or as a subscription (which took a long time to implement:)). I don't know whether the message is clear, whether the idea could work and if there are things that we could improve (of course there are :))
Any suggestions or feedback will be greatly appreciated. Thank you very much.
I hadn't considered an API - what do you have in mind? An HTTP post & response? What would you use it for? I just hadn't thought of this since the graphics libraries and routines are readily available. An API seems to cut out any possible ad opportunities - is an api something you'd be willing to pay to use? Thanks for the idea.
An HTTP post & response could be an option. It would just open the possibility for other services to integrate with yours, there making it more flexible and open to a larger audience. A freemium approach could then be a possibility (where one starts paying after a certain amount of daily API usage)
