Just looks like normal wear and tear to me.
The dont NEED to be fixed. If you want to clean them up:
You can take an edge guide and file and file down the edge tip to tail a few times and should see it go away. Then take that file out of the guide detune under foot and soft gummy stone it down for further dulling.
It may not be a bad idea to take your shit in for a shop tune (base and edge).
