Comments, please on Turkish Knife, made from a file

I was reading about the forging process of a blade. During the processes of heating and cooling, the metals properties are altered. At one point of this process a blade would have the metallurgic properties of a file i.e. very hard and brittle. This is then reheated and cooled to 'soften' the blade to increase its ability to absorb blows (becomes less brittle and hardness is reduced). I can only assume that the file is annealed (made 'softer') to allow it to be forged without fracturing. If this is the case it would make sense that the teeth would be beaten into the surface of the metal and stretched.

I tossed out my idea because of my background and having made a fair amount of tools from old files, including a pretty ugly knife or two but mostly chisels and scrapers. Forging does indeed kind of work the file marks in. But this knife appears more ground or filed to me than forged.

Can you tell if it is forged or ground. (edit--Well just reread your post and did say ground)

Would the method of manufacure point to it's origin? One culture annealing then grinding or filing and another forging?
