Oh no, your 9 has a chip in the blade near the handle, looks to be the size of a man’s finger, better send it back to Ka-Bar!
You can also use nail polish as a resist and create cool patterns or lettering and such, and after the etch, clean it off with acetone.

On that BK9, I just splashed the nail polish on and wiped it down with muriatic acid.
Nice, ThanksThis was also done with salt and vinegar with nail polish resist
