Thread: Alternate types of GlassStones ?

if i remember correctly shapton pro is for carbon steel
shapton glass for stailess steel
and the new shapton glass for carbon steel (japanese steel) and will eventualy replace shapton pro

i think they all work good on any steel except that if you use them with the other steel it will not be as
shiny. it will leave it a little foggy or hazy

this is what i remember from last year discussions

On Shapton's website they have a FAQ that states that the 12K Pro is for stainless. They say that it will load up when used with carbon and that the other pros will not. I have the pros including the 12K and I have successfully sharpened both carbon and stainless with them.

Not to contradict Russel as I imagine he has probably forgot more then I know about honing but the woodworker's forum that I mentioned earlier here seems to have a different view of white versus blue steel. This poster Scott's info gives me the impression that blue steel would be the better choice for razors but I am a neophyte in metallurgy.

Perhaps they are talking about two different things ? Could this be blue or white as applied to the small world of Japanese woodworking tools? Awhile back I bought a razor stamped Blue Steel and in googling the term came up with a definition on the wiki that didn't mention white steel.

I don't really know where the controversy stems from, some guys say White takes a sharper edge, some guys say Blue, and it probably comes down to a question of the particular smith at some point.

But from the standpoint of the metallurgical properties of the steels, IIRC, chromium and tungsten carbides will limit how fine the grain of the steel can get. Finer grain allows for a thinner edge to be maintained but, again, the difference is going to be affected by the smith as well.

The only difference that is said to be noticeable is the increased edge retention of blue steel, but then again, there isn't a whole lot of info as it applies to razors.

Sorry if i made a confusing post. I think if you find "blue" in a description that is not specifically referring to Yasuki factory's aogami, then it isn't "blue paper"; usually it means "blued"
I extended the descriptive to include anything nearly similar such as calling Swedish plane making steel- blue steel. So the question is what alloy steel products were available during the period of straight razor production. Prior to 1920 or just a little earlier there probably wasn't any.
