I am curious as to the actual blade/shaving head/ handle configuration all the safety razor bros use. Any razor with some type of not sharp protective guard near and paralell to the extremely sharp blade is a "safety razor." So how retro are you going? Which of the razors in my collection fits your definition of shaving like a man?
The cartridge shaving heads common today have one or more blades embedded in a block of plastic that also has the safety guard. They are a variant of safety razor in that the guard is part of the disposable blade. These were introduced in 1970 with the single blade Wilkinson bonded blade. The number of blades per cartridge has increased about once a decade since.
Are you going back to the razor described in this patent for "new and useful improvements in Safety-Razors", filed in May 1880 by Frederic and Otto Kampfe of Brooklyn, New York? This is the first official mention of the term "safety razor." The blade on this razor had to be honed and stropped regularly to keep it sharp. Not an easy task.
I am guessing most are going back to the pre WWI (1904) style safety razor with disposable blade patented by King Camp Gillette in 1904. This is the first not resharpenable disposable razor blade shaving system. Two sides of the blade were sharp and the shaving head held the extremely thin blade tightly to make it rigid enough for shaving. The head also incorporated a safety guard for each sharp side of the blade. After the blade was used and dull, the blade head opened, the used blade removed and discarded, a new blade inserted and the head closed.
The army issued Gillette razors to soldiers during WWI and allowed the soldier to keep them when they mustered out. The Gillette philosophy was "give away razors. Sell blades."
Gem Cutlery and the American Safety Razor Company made single edge blade razors. They are similar to the Gillette design, except that only one edge is sharp and the other is wrapped to protect the user's fingers while changing blades. Gem single edge razor blades are still commonly used for industrial purposes.
Others may be using the injector style, patented by Jacob Schick in 1926. This improved safety because the user never had to touch the sharp blade. The shaving head included the safety guard. 20 blades came in a cartridge. The cartridge tongue was inserted into the shaving head, the cartridge slide was pushed forward to inject a fresh blade into the shaving head, while simultaneously pushing the used blade out. If the user was smart, the whole process was done over a trashcan so the ejected used blade fell into the trash.
Wilkinson Sword developed and started selling stainless steel razor blades in 1962. They mimicked the Gillette style double edge razor. However, they didn't rust and lasted much longer. Carbon steel blades are still available, but hard to find. Some swear they give a better first shave, but not second.
Or are you going really old school, back to a circa 1762 invention by French cutler Jean-Jacques Perret which added a protective guard to a regular straight razor.
So, just how far back in my collection of razor styles and types do I need to go to shave like a man? I am not going back to rusty carbon steel blades. Not happening.
