Due to their fine steel and precision grinding, our blades are incredibly durable. Our German partners attest that they will perform well for long, long periods of time. Of course, because Harry’s blades also happen to be affordable, we couldn’t blame you for wanting to indulge in the luxury of changing them a little more frequently. Many guys tell us that they like to change their blades every 6-8 shaves. Whether you change blades every day or every month, we’re here to help talk you through it.
