I have an idea! If my posts are scielenced on Spyderco forum - I will just copy it here.
Why to waste good posts? As well this may answer some questions and show what Spyderco is hiding, plus here I will not be attacked by hysterical fanboys. Seems like everybody win!
Blue steel has little tungsten in it to make heat treatment bit easy for smith who can not yet catch pre tempering temperature by eye, blue steel has tempering
window wider. This tungsten does not make it performance better.
This still is quite corrosive, but it outperforms VG-10 and pathetic CPM S30V by far.
There is no such things as this steel can be sharper then other as well as this steel is harder to sharpen.
Most of this talks come from people who do not know proper sharpening technic - do not listen to them
they are not an experts.
Vikings use pattern in their swords to make them stronger. Combination of soft iron and hard steel with certain spring like pattern adds
some spring like properties. Modern days it is nothing but pattern, which somehow I do not like and performance is not very good
it actually worse then component performance. Unless it is suminogashi - where layers made the way that only good steel ends up
on the edge.
There are some urban legends about damscus better performance - like damascus serration etc... You may see them in Sal's post.
But it is not really the case.
Modern layered steels has nothing to do with old Damascus swords or old Viking spring patterns - it is just catchy sales person story.
Now days it is just ornaments and skilled craftsman may do damascus which performs as good as regular steel.
