Question :
How does the DE blade market exist at all now ?
In my American city a double edged razor is impossible to find , the blades almost as hard to find , and the blades which are available are generic brands rather than quality blades like Derby , Feather, Sharp , Astra, etc.
Is the international market outside the USA the main market for DE
shaving ?
If yes , which countries ?
In USA , it seems relatively few people under the age of 60 are even aware of DE shaving and those who are think of it as unsafe because the equipment is largely unavailable on store shelves. They think of a "safety razor" as one which uses a disposable plastic cartridge and doesn't have exposed blade edges.
In general, the DE's seem to be popular in countries not considered first world, I have read. Easier and cheaper to make. I don't think patents still apply to them, but I dont' know that for sure.
I have also read that as countries become more affluent, the preference for cartridge blades grows.
