Can anyone suggest how to re-etch a blade after the knife edge has been established and sharpened? Like an idiot I did a final strop on my jeans and accidentally ran the blade across my pocket knife clip causing a scratch into the etched part of the blade.
I don’t think I’m steady enough to apply nail polish in a straight line to protect the sharpened edge without it looking like crap.
 
Is this a pattern welded blade? Mono steel blade? What steel(s)? How fine a finish on the blade? What did you use to darken the blade?

Need more information.

Welcome Northern Grind.
Devin has asked what we would need to know to answer your question.

What you will need to know is that this is just the first of thousands of scratches. The "etch" is just a surface oxide. It will wear, scratch, and dull with any use.

Mono steel finished at 1000 grit. Darkened it with Ferric x 3 and then coffee x1.
 
If it has a coffee etch, it may not all go away with the Q-tip and FC.

Again, FC and coffee "etches" are just surface treatments and are only a few millionths of an inch thick ... and not hard.
