The differences between electric razors and blades include the power supply, time of shaving and the quality and feel of the shaving experience. Depending on the type of electric or blade razor, each has its advantages and disadvantages.
The most obvious difference between electric and blade razors is that electric razors need to be plugged in or have a battery to operate, while blade razors rely on the user for operation.
Electric razors have a clipping mechanism behind a screen that shaves as it's moved over the face; the screen prevents accidental cuts. This type of razor doesn't require the user to wet the face or use shaving cream. For these reasons, electric razors are often deemed more convenient and usually allow users to shave in less time than a conventional razor.
Blade razors come in two varieties: safety razors, which are the standard type of disposable or replaceable-blade razor, and straight razors, which are very sharp, unguarded thin blades. Straight razors have fallen out of favor in personal shaving but are still sometimes used in shaving and barber shops.
With either variation, blade razors require a wet shaving surface and a lather of shaving cream. Users must be careful when shaving with manual razors because it's easy to cut the skin. Because of the added preparation time and caution taken in shaving, blade razors usually take longer to shave with. However, these razors get a closer and cleaner shave than their electrical counterparts.
