How often do I need to replace the blades?Updated 2 years ago
OneBlade customers see an average of 2-3 shaves per blade. If you notice tugging on your hair or any discomfort on your skin it's time to replace your blade.
There are several factors that affect how long a blade will last:
- How dense your facial hair is (hairs per square inch)
- How thick your facial hairs are (thickness of each strand)
- Whether or not you wash your face before shaving
- How much of your face you shave
- How often you shave
Factors #1-4 all affect how much the blade edge is getting worn down per shave. Hair density, thickness and coarseness all vary greatly between individuals. More hairs per square inch, thicker hairs, and more wiry (as opposed to soft) hairs will dull the blade faster. Research has shown that typical facial hair on men can be as rigid as a hollow copper wire of the same thickness. The hollowness of facial hair allows for absorption of water, which helps to soften the hairs. Washing your face or showering before every shave will soften your hairs for a more comfortable shave as well as give you more use out of your blade.
Factor #5 has to do with how much time the blade is exposed to oxidation over its lifespan. The very first shave with a Feather FHS-10 blade begins to wear on the protective platinum and PTFE coating which allows for a slow oxidation process on the steel. More time to oxidize means more dulling. If one person shaves every day, they might get 5 comfortable shaves. If another person with similar facial hair only shaves once a week, their fourth and fifth shaves are going to be far less enjoyable due to the blade sitting out four and weeks by then.
