No, it's not. If anything there is a belief that DE blades actually stay sharp and last longer than cartridge blades. I don't know if there's any evidence to that, but the effect is that many DE shavers keep their blades for a number of shaves. I suspect that some are more inclined to swap blades frequently because the blades are so (comparatively) cheap.

- betterbeehome 7y agoIf you use hot water to shave, Gillette blades dull very quickly. If you use cold water, they last longer than DE blades. It mostly has to do with the plastic coating on the cartridge blades. However, if you're skilled at shaving with a DE, technique actually prolongs your blades life into many shaves with the same razor.
- heelix 7y agoDrying the blade makes a difference too. For me, the most noticeable difference is my daughter would never use my DE safety razor on her legs. The cartridge style.. well.. they dulled out way faster than they should have from my usage.
- prepend 7y agoI used Feather blades and would change them after each shave. I would use each side twice to get a close shave. I’m not sure how much you could reuse a single blade. Of course I think it was like $25 for 100. For comparison, I’ve also used a Mach 3 blade for a month, so the Mach 3 blades lasted longer than a single blade but cost much more $40 for 10.
