All opinions are welcome regarding edge retention, how keen an edge does it take, etc. M4 is easy to sharpen and takes a very sharp edge and holds it. VG-10 may not hold an edge as long but it gets real sharp also. Actually, "getting sharp" isn't really a concern with any steel I've seen on Spyderco knives. Anyway, I ordered the knife and unless I get a whole bunch of folks saying super blue steel is horrible I will get the knife (not cancel the pre-order). When I placed the order this morning I was and still am expecting better than VG-10 (at least) but I haven't heard anything about super blue being as hard as ZDP. I don't know much about steel so comparing super blue to VG-10, S30V, XHP, ZDP or M4 would give me a better idea of blue steel than any technical explanation. There's bound to be some variance in opinions and I'm not very picky about blade steel but I hope I will like the super blue more than some of what I've used. Anyone know the Rc hardness?
I have the FRN/VG-10 D'fly so a grey FRN D'fly with super blue I hope to be an improvement in blade steel. A change in handle color is nothing to me even if it is a sprint run.
Super Blue is Spyderco name for Aogami - steel with blue label sometimes translated as blue paper steel is second choice for all Japanese custom knives.
First is White label steel. Both carbon steels steels with simple composition, one which provides best performance for blade, but it is not rust resistant.
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.
