Our razors are made to last for many years, but they do require care. Conditions that impact the metal include humidity, low oxygen, high salinity, or poor air circulation environments. Razor blades should not be kept in razors in humid conditions for extended periods of time as metal is subject to degradation if left unattended. When changing blades remove the blade, clean it with soap and water, and dry thoroughly. Store in a cool, dry place if razor is used infrequently.
