But I have used a SGPS FK before, and I just don't like the steel at all. Deforms and dulls too quickly for my tastes. But my uses don't require easy sharpening.
SGPS shouldn't deform and/or dull quickly at all!
I think I know what You are saying,as I had similiar thoughts on my first FK, the TK1.
I couldn't figure out why it didn't hold the edge as good as a cheap laminated carbon steel Mora.
It took me several months of learning to sharpen and hone the convex powdersteel, before it started to hold the edge, as it could be expected of such a premium knife.
This also meant that the factory edge and the steel right behind it, was replaced with a new edge.
Today that knife is my benchmark,when I measure good cutting qualitys, but I have so far not managed to equal the TK1.
Without the factory edge it has turned out as a very good knife, perhaps my best 4" blade.
Today I have several 3G steel knives and the TK2 feels much harder already out of the box.
It doesn't deform or dull as the TK1 or as You describe.
Instead it keeps almost all of the factory edge, as it is so hard to dull it.
Same with my TK3 and SK3.
The TK3 was flatground with a bevel and has been convexed, with the help of a diamond DC stone.
The SK3 Juni is so hard that the original edge grinding marks refuses to go away.
It just don't go dull in regular use!
It can be dulled but it takes an effort or accident to do that.
My WM1 in 3G has had 3 accidents,were the tip hit the concrete workshop floor.
The first two hits damaged the tip and it had to be resharpened.
The third time the tip took a piece out of the concrete, but stayed unbroken.
All this various experience with 3G over the last 6 years, had made me think and discuss with Fällkniven, why I feel a difference between the knives.
Firstly it's in the sharpening skills of the user and in my case it has been a learning curve that takes a lot of time.
Both Peter and Erik has said that the differrences shouldn't be there and every batch is followed by it's own heat-treatment protocol including a test blade.
So that leaves me very puzzled.
Is there a differrence as I, Hardheart and others can witness about from using the knives or is it in the sharpening skills?
The maker of the carbon steel blade in the broken Sami knife mentioned before in this thread said:
-Just grind to new steel as the edge sometimes gets overheated in the grinding process!.
That's from a maker of blades!
Maybe this is what it's all about, overheating when grinding the factoryedge?
