What is the difference between safety razors and cartridge razors?

Safety razors and cartridge razors differ in several key aspects. First, the design: safety razors have a single, double-edged blade that is held in place by a protective guard, whereas cartridge razors feature a plastic handle with a removable cartridge that contains multiple blades. Second, the shave experience: safety razors require a skilled technique as they provide a closer shave and require more manual control, resulting in less irritation for many users. In contrast, cartridge razors offer convenience as the cartridges come with multiple blades and a pivoting head that adjusts to the contours of the face, providing a quicker, but potentially less precise shave. Lastly, cost: safety razors are generally more cost-effective in the long run, as replacement blades are inexpensive, while cartridge razors tend to be pricier due to the need to frequently replace entire cartridges.
