Now these marks...
The heavy dark ones might be old teeth from some old crudely made rasp. The do appear to taper and fade...the cutting edge is on the right isn't it? But are we sure?

The cross hatching on the spine doesn't make it a file.

Hi DD, thankyou for your input...the spine of the knife is effectively the thickest, and therefore the 'teeth' of the file are more obvious. The blade is ground,which tapers to the edge, this would remove the 'teeth' as the file is made thinner to form the cutting edge. The cross hatching on the spine is not the 'remains' of the file showing, it has been incised, probably with a fine chisel, as decoration. It can be difficult to analyse a blade from a photo...its easier for me.....its in my hand

I always welcome ideas, no matter how bizarre, strange or 'commonsense-icle', this is how things are learnt, not by repeating the same ideas but by challenging them. If the ideas are right they remain unchanged but if a new idea or thought upsets the 'apple cart'. The established idea has to be reviewed, altered or thrown away....... a sort of 'evolution of knowledge'
......... oops......just fallen off me soapbox

Do not forget that the cutting parts of the file are forged into the metal, these will stretch as the metal is worked. There will be remnants of file structure often as a scale pattern that can be anywhere on the blade unless ground off.

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?
