Brand New Carbon Cx Razor - The Cx-904L

This is a Cx razor machined from 904L stainless steel. I'm not at all familiar with this metal. It is similar to 316L according to Carbon, but with a much higher alloy content and 1-2% copper. This grade of stainless steel is reserved for the most prestigious industries, such as high-end watchmaking, including Rolex ®, commercial diving and the offshore oil industry. 904L stainless steel is renowned for its unparalleled durability, corrosion resistance, and captivating luster. I'll take their word for it! 

It comes with all the web plate options available, has a 92mm handle (3.6"), a 13mm handle diameter (.5") weight 88 grams, and the cap has a traditional Perlage pattern underneath. Luxury is the word as the razor comes in at $600.

Curious as to any ones thoughts on it and experience if anyone picks one up.

Thanks for the post metal_shavings ...really appreciate it.

I wrote a blog about the material when I was researching the metal, I thought this might help and answer some questions:

No problem, Sean. I have my 316L and I love it. I'm upset I missed the Copper release. I bought a handle sometime back used but have no cap and plate for it. Eventually! I will check the blog out I am curious. I know there are many types/grades of steel and other metals also.

Got it! Thanks Sean!

Really cool CarbonShavingCo. !

As a Rolex fan I wanted to chime and point out that Rolex uses a proprietary version of 904L that they call “Oystersteel” and it isn’t the same thing at all. At this price point I’d expect something like grade 7 titanium, hastelloy, inconel, etc.

In reading the blog, you mention a higher difficulty in machining the metal. Does this also translate to a larger margin for error and/or ruining the razor?

Ooo I like the perlage. Nice touch!

metal_shavings the big challenge with machining this material is very few people have done it. Very little information is publicly available about how to machine it...we had to explore a few techniques and tools. We were not sure we could even do it...we lost a lot of 904L pieces during milling and finishing. The higher % of alloys (Chromium, Nickel and Molybdenum) make it very difficult.

Finishing was also unique...rough finishing took time. Fine finishing took extra steps...

Deus Vult Here are some links and a Rolex videos on the subject:

904L is a very specific specification(redundant?)..."Oyster" steel as an example might have more or less Molybdenum but it is still 904L. Omega called their version "Uranus" steel which was also 904L. I believe both names are trademarked.

The Cx-904L is not made with "Oyster steel" nor "Uranus steel" but it is still 904L like both of them. I thought about our own name but decided against it.

I ran into a similar question with "Timascus", 2 grades of forged Titanium Damascus. "Timascus" is a trademarked name(and process)...our blacksmiths call their Titanium Damascus, "Damtanium"(process a trade secret). "MokuTi" a play on Mokume-Gane and Ti is another name for Titanium Damascus...I believe it is also trademarked.

Appreciate the comments,
Sean
