Not to start a witch hunt but looking at the first image of the "CS" knife... Look at the lighting on the tang bolster, and the pin placement.
You can clearly see a transition in the lighting reflection as if the pin was hammered out, and slightly bent the bolster. I am sure you would not feel it or see it with the naked eye UNLESS the light caught it at the right angle. In this case the lighting does not lie.
Much of what I do is paint, fabrication, body work and light/angles do not lie
I only say this because AFTER the pin is peened in, the bolster is ground, and if it was undisturbed there would be a perfectly flat bolster.
That bolster is not flat. (Insinuating the blade was removed to change or modify)
Someone versed in scaling (autocad/Blender) could prove that to be a Scharade (from the images) or prove it is not.
