The Rockwell razor made a bit of a stir when it was released a few years ago. Ever since adjustable razors were introduced, they have been mechanically more complex than a three piece razor. The Rockwell Razor bucked that trend, and bucked it hard. The Rockwell razor is as simple as a three piece razor because it is a three piece razor. It is as simple as that.


I was a little surprised that such a simple concept was patentable. After all, it is over a century since the original three piece King Gillette razor was patented. I guess it just shows that simple ideas can be hard to come up with.

The patent is quite interesting reading too, less obtuse than many older patents. The text also goes into the background for the invention, which I think is a major improvement over some patents I’ve read. To give an example:


Quote:The most popular modern shaving implement uses cartridge based razors that include a number of single-edged razors in a disposable cartridges. The consumer cost of these disposable cartridges is quite high and has been an impetus for the return to traditional wet shaving using double-edged safety razors. Refilling a traditional safety razor can cost under 10 cents whereas modern cartridges can cost well over $2 to replace. Today’s modern razor cartridges can also irritate the skin more than needed due to the multiple blades.


Remarkable clear and concise, just like the patent drawings.

Full patent can be read at Google Patents, as usual. If you enjoy patents for razors and shaving related accoutrements, I got a page full of them.
