G-2?

[decorum]

Probably a daft question, but I'll ask it anyway
Firstly a bit of background!
I've owned my two Spyderco knives, a 'Rescue' and an 'Endura', for many years and have just noticed (or possibly re-noticed - my memory is a bit unreliable!) that stamped onto both blades is G-2. Initially I wondered whether G-2 meant '2nd Generation' but a bit of digging sorted out that the 2nd generation Endura was the same as the original but had a stainless steel handle, 'So' I thought 'G-2 must be the steel used for the blade'. The official Spyderco web-sites' history/archive section doesn't appear to mention G-2 steel and a quick google for it turned up this site: http://www.bluescopesteel.com.au/go/product/galvabondandreg-g2-g2s-steel which lists the some common uses of G-2 steel - tube, air-conditioning ducting, air-conditioning panels, meter boxes, trailers, partitioning systems, cable trays, scaffolding, planks, rendering mesh and feeder troughs - no mention of it being used for making sharp stuff.
And so, finally, the question: Does G-2 signify the steel?

Thanks Tadpole, I don't think I'd have ever found a link to an alternative name! :You_Rock_
With your help I found this: http://www.spyderho.com/blog.aspx?tab=3

To quote the site 'Gingami 1 : GIN1 steel, translated to English from Japanese means silver paper. This steel was developed by Hitachi and was first used for our spyderclips! GIN1 has also been marked on blades as G2 Steel, when you see the marking, they mean the same thing. This change in markings from G2 to GIN1 was done to avoid conflict with Gerber who was also using the steel in its knives and blade markings until 1994 when they discontinued its use. This steel was first class and one of the best steels being used in Japan and America for blade steels in the 1990's.'
