A double edge razor is a type of shaving tool that uses a single blade with two sharp edges. This design allows the user to flip the blade for a fresh edge, making it cost-effective and environmentally friendly. The blades are typically made of stainless steel and can be easily replaced, providing a close shave while minimizing skin irritation. These razors are often preferred by traditionalists and those seeking a more sustainable alternative to disposable razors. They require a bit of technique to use effectively, but many find that they offer a superior shaving experience compared to cartridge razors or electric shavers.
