Double-edge blades: sharpness versus smoothness, how long a blade really lasts, and why a sampler beats picking a favorite on faith.
Blades are the cheapest variable in wet shaving and one of the most consequential. They cost pennies each, they are the only genuinely consumable part of the kit, and swapping one changes the character of a shave more than most people expect.
The two properties that matter get conflated constantly. Sharpness is cutting force, how easily the edge severs hair. Smoothness is what the edge feels like crossing skin, and it comes from coating and grind consistency. The sharpest blade available is not the most comfortable one, and a blade that feels harsh is often rough rather than simply keen.
Blade life is personal and should be measured in shaves, not days. A blade dulls from cutting, not from sitting, so a coarse beard and a three-pass routine will burn through blades far faster than fine growth and a single pass. The only rule that always holds: when a blade starts to tug instead of glide, it is finished, and at these prices there is no reason to push it.
Because response is so individual, a variety sampler is genuinely the right first purchase. This hub covers blade comparisons, the sharpness spectrum, and how to make an edge last.

The five-blade cartridge was sold to you as progress, but the mechanism it uses to feel smooth is the same mechanism that causes ingrown hairs and razor burn. Here is what actually changes for your skin when you switch to one blade, and what the switch honestly asks of you.

The honest answer is not a number of days. A double-edge blade lasts most shavers three to seven shaves, but the real signal is how it feels, not the calendar. Here is what actually wears a blade out, how to tell when it is done, and the myths to ignore.
