The traditional Straight Razor dates back to the 1680's. It's gone by many names like the cut throat razor -- think Sweeney Todd, or the old fashioned razor. These razors are a throw back to a forgotten about era due to fancy marketing of more profitable cartridge razors. The reason these razors primarily went by the way side is it's not overly profitable for a company to sell you a razor that can last you your entire life because you are not likely to buy again. That's what the straight razor offers you. The straight razor has to be honed and sharpened which leaves each man the master of his own destiny. If you choose to get the supplies to do so and learn that craft you'll have an amazing razor for life that you never have to spend another dime on. It's one solid piece of metal with a blade on the bottom side.
The Shavette Straight Razor is your barber's razor. In most places barbers are not allowed to use a traditional straight razor because it uses the same blade on every shave. The shavette was created to give the same type of shave but with a removable blade so that each person uses a fresh and sanitary blade for each shave. The shavettes have a latch on the top which allow it so slide open an a new blade to be slide in with minimum effort. These are incredibly popular because the blades are really inexpensive and provide an impeccably close shave without having to hone or sharpen a blade.
