Derby 100 Extra Shaving Blades
Amazon's catalog no longer lists this product (checked 2026-11-02). The name comes from the link HN users posted.
Razor blades are small. Assuming parent poster shaves every single day of that ten years, and each blade only lasts for two shaves, they'd need about 1830 blades.
That's 19 boxes of these, which probably fit in a shoe box.
