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
