Looking at razor blade steel patents, to get a better idea of their history and development, along with the desired characteristics, I came across this:
Amorphous Razor Blade Steel Patent


And a little more in amorphous steel:

Amorphous Metal

I think a knife made out of this might be interested to test out and play with.

The first link is a patent to a steel composition that varies so much you can probably find more than a dozen steels that fit into that description. The patent is pure BS.

The second link is interesting, however.

I think the first link isn't talking about the composition of the steel, like how much carbon ect, but how it's made, something about centrifuge, that's explained in the second link which is why I posted both of them together, I couldn't make heads or tales if the first Iink, the patent. I could be wrong.

That is typical of steel patents (and material patents in general), they are very wide scope in composition. In general when you develop a steel you develop more of a family of steels not a particular composition. Imagine for example you patent a particular steel and all I have to do is just vary the composition by a tiny amount and just make it and claim it isn't under the patent.

A steel patent is basically functional, what are they trying to achieve and thus the compositions can be extremely broad.

0.5 to 5.0% carbon, 9.0 to 14.0% Cr and 0.5 to 8.0% Mo, 0.5 to 8.0% of B+Si

Are these two examples below the same family?

0.5% C, 9% Cr, 0.5% Mo, 0.5% B,Si vs 2.2%C, 14% Cr, 1% Mo, 1% B,Si

Cobalt,

Patents have some kind of scope, what they are talking about, in that particular one it is the amorphous structure, and the fact that class of steels, through balancing of the elemental composition produces a desired hardness and microstructure.

It is common for those types of patents to have huge ranges of elemental values, for example :

- [www.google.com]

- carbon values range from 0.1 to 2%
- vanadium ranges from 0.5 to 14%
- 16 to 30% Cr

These are massive sweeping ranges of elements. However in the patent they won't just say any steel in that range is in the patent, they have to be in particular relation to each other, made in certain ways (forming), etc. .
