Do men in poor countries still shave with a cutthroat razor? Reusable and repairable products take time but give certainty. I hope a happy medium will be reached between Chinese room products and simple skill based ones.
Double Edge razors are also a thing. I use one myself because I don't like the cartridges clogging, and it's a lot cheaper. Like 20$ for the razor and 10$ for a "lifetime" of blades.
Old fashioned razors are more reusable and repairable than modern razors.
Not only reusable during its intended purpose but also after.
