What Your Father Didn't Teach You About Shaving


How Blade Lifespan Really Works

Ask experienced wet shavers how long a blade lasts and the answers rarely agree. One replaces after three shaves. Another uses the same blade for weeks. Both may be convinced they're right.


The confusion persists because blade lifespan is treated as a number to discover rather than a process to understand. “How many shaves does this blade give?” sounds reasonable, but it assumes blades fail in uniform ways.


They don’t.

The SOTD Mismatch

Shaving cream and soap collections often grow for good reasons.


Curiosity, seasonal scents, artisan experimentation, community recommendations, and simple enjoyment all play a role. Acquisition is active and social. Usage is private and repetitive.


What surprises many shavers is not how many soaps they own, but how few they rely on when consistency matters.


Daily shaving rewards familiarity. Collections reward exploration.


Those two motivations coexist, but they don’t operate at the same time.
