In Ritchie and Stewart's "Standard Guide to Razors 3rd Ed.", it says on page 14 "...the straight razor did in fact originate as a simple, straight-frame instrument that folded like a pocketknife, but never acquired a backspring. It was really very similar to the Old English 'penny knife' that was so common during the seventeenth and eighteenth centuries. It is likely that it acquired the name 'straight razor' from this period in it's development."
In one of Krumholz' other books, "The Complete Gillette Collector's Handbook," it doesn't look to me like King Gillette used the term "straight razor" in his advertisements, to distinguish his invention from what was in common use during that day. The term "Safety Razor" wasn't patented until 1911, though I see the term used in Gillette advertisements as early as 1904. In the first advertisements from 1903, Gillette simply referred to straight razors as "razors," and his own invention as "the Gillette razor."
Here is King Gillette quoted in this same book writing about his invention vs. straight razors, which I quote again here for the entertainment of straight razor shavers everywhere. I get the feeling here that Mr. Gillette is the sort of man who might have re-painted the Sistine Chapel ceiling with a power sprayer:
A razor is only a sharp edge and all back of that edge is but support for that edge. Why do they spend so much material and time in fashioning a backing which has nothing to do with shaving? Why do they forge a great piece of steel and spend so much labor in hollow grinding it when they could get the same result by putting an edge on a piece of steel that was only thick enough to hold an edge?
