At about the same time as the original Gillette safety razors were offered for sale, Henrie Clauss filed a patent for a spring loaded hoe razor. It was a reasonable straight forward razor, using a single edged Christy-style blade. So let us have a look at what made it stand out from the crowd.

Like so many razor patents, the patent text describes the invention as containing “new and useful improvements”. And while it might have been novel – or at least novel enough for a patent – I’m unsure of the usefulness.

As I briefly mentioned in a post a couple of years ago, the idea of a heated razor is old. As old as the idea of self-lubricating razors and self feeding brushes. And a heated safety razor makes about as much sense to me. It may make more sense if you’re bathroom is frigid and you don’t have endless hot water straight from the tap. And it obviously made some form of sense to Leon and Thomas J Henderson back in 1935 when they applied for a patent for their variation on the theme of heated safety razor.
