All About Pocket Knives

I wanted to show this Mariner that I bought that came with a small collection. This knife is in great shape but I was wondering about the serrated blade. It is pretty sharp and will cut a stiff piece of paper. Does the edge look like it should be sent back to Spyderco for a new grind. I don't plan to carry this one, Just not my style but I am interested in selling or trading for a traditional knife of comparable value.

It sure is worn down.
To be useful it certainly needs reground by somebody.

Thanks!
