Very nice knives and thanks for sharing. I have grown very fond of the Fallkniven Knives over the last year. I have been holding off on buying one, but made the plunge on Saturday. Bought a P/3G with the Blue handle for my wife.
Can anyone tell me a little about the blade steel being used on these knives. I am not firmiliar with 3G.
thx

I'm sure you will be pleased with the P/3G. It has been my EDC knife for the past several months and I really like it. Great choice:thumbup:
As far as the steel goes, I'm no expert so this info is just a regurgitation of what I've read/heard from other sources.
3G is also refered to as SGPS (Special Gold Powdered Steel). It is a hard steel, 62 HRC, and is considered to be among todays "super steels". (I have also seen it refered to as Super Gold Powdered Steel)
Because it is hard it will hold an edge well, but can be brittle and will chip or break rather than bend much. I don't think chipping should be a concern if used for cutting as intended. If you pry, or chop hard objects with this steel it may chip rather than bend or nick.
Fallkniven laminates their core of SGPS (or VG10) between two layers of softer steel (420J2 I believe). This gives the blade strength against breakage while allowing for excellent edge retention with the harder core. Both 420J2 and SGPS are stainless steels so the blade will have good to excellent corrosion resistance.
I'm not certain, and this is a bit of an assumption on my part, but I think Fallkniven's reference of 3G identifies One layer of Gold powdered core between Two laminated layers. In other words, it isn't that 3G is a specific type of steel, but rather it references the 3 layer laminated blade construction with a "G" core.
Harder steel can be more difficult to sharpen but I have found a combination diamond / ceramic stone or rods to work well with my Fallkniven knives (3G and VG10). A few quick passes and they are nice and sharp, but I try not to let them get very dull in the first place.
Here is the composition of the SGPS steel:
SGPS (edge)
C - 1.40
Si - 0.50
Mn - 0.40
P - 0.030
Cr - 15.00
Mo - 2.80
S - 0.030
V - 2.00
More information can be found on Fallkniven's site: http://www.fallkniven.com/next-index.htm
Hope this helps a bit.

EDIT: SGPS is manufactured by Takefu Special Steel Co. Japan. Takefu also manufactures VG10.
