John Heissenberger was a fairly prolific inventor at the turn of the last century. And in between such fun things as machines to exhibit illuminated pictures, punching machines, and mail-delivering apparatuses, he did take the time to invent a couple of wedge razors.
For those unfamiliar with the term, a wedge razor is a safety razor that uses a wedge shaped blade. Think a section of a straight razors, instead of the flat blade of most other safety razors.
We’ve talked about razors that stretches the skin before. But I can do you one better today… It is a razor that stretches the skin and has a lubricant dispenser built in. And as a bonus it still looks like you can shave with it with it – unlike some patented razors I could mention. So what did William Miller get a patent for almost fifty years ago?
Once you have a razor, it must be stored between shaves. And while I’ve looked at a number of cabinets and othersolutions before, I think this is the first one made to keep your razor dry and corrosion free. Filed in ’71 by Jack Cobb, the apparatus for storing cutting implements looks sensible – and pointless.
There is always someone who can’t manage to handle both a razor and a brush. This has lead to a largenumber of self-latheringrazors. So Saul Hackmyer was in good company when he filed a patent for a self-lathering razor in 1971.
Where he differed from most of the patents I’ve discussed before is that he designed his invention around canned goo. Or as the abstract puts it:
Rotary, or revolving, razors isn’t a new idea. I’ve featuredseveralof them before. That did not stop Hirotsugu Matsuura from patenting one in 1969, with an interesting variation. He described it as being a rotary spare blade razor. The idea seems to have a plurality of sharp edges available as needed, without having to open or take the razor apart.
The blade carrying element of the razor was also replaceable, making this an early form of cartridge razor.
A safety razor is often said to be a razor with a guard. So a safety razor blade is therefore a blade for a safety razor. Or is it a razor blade with a guard. Is it, in fact, a safety-razor blade, or a safety razor-blade?
According to Alfred W Ferrara, it is the later. So lets us see what imaginary problem he sought to solve with his invention:
