What kind of steel is used in the Hart razors? What is 0-1 steel, Stainless or Carbon?
Quote from the website:
"Every part of a Hart straight razor is created and assembled in the U.S.A.; from the steel and the hardware to the durable injected mold silicone scales. Our steel is tested at a Rockwell hardness of 63,"
www.hartsteel.com I purchased one of these razors a couple of weeks ago, it is off for some customizing from one of own artists here. I am really looking forward to shaving with it! :)
01 is a oil quenched carbon steel. makes a hell of of a knife should make a great razor
The Hart artisans use O1, which as others have indicated is a high alloy carbon steel. It's good stuff. :)

O1 is a very common alloy of Oil Hardening Tool Steel... Probably the most common. When taken to the limits of it's range on the Rockwell scale, it can be quite brittle. I think there are better steels for an edge, such as HCHC (High Carbon High Chrome D2), but those steels carry other liabilities for fabrication, such as loading up grinding wheels...
Here is a post by Tim Zowada detailing the particulars of the Hart razors. I haven't gotten one myself yet but it is on the list aways down. :)
I might suggest that it can be difficult to achieve the Bainite phase, whithout going to either Pearlite or Martensite, and even more difficult to assess whether it has been achieved or not.
But, I'll add here that mt base of knowledge is not as a razor artisan, or in any way connected to the straight razor. My experience comes from a lifetime as a Tool & Die Maker. Our cutting angles were very different, and we were concerned with cutting and forming metals, not facial hair. That said, I have worked with 01, both in pre and post heat treated states. We also did some of our own heat treatment, but that was very crude compared to the experts.
So, I suppose some of what I may add may or may not apply to the world of the straight razor..
I will let the reader decide if any of it is valid or not...
Knowledge is Power, and I don't think that anyone can attain too much of the former.
