Good luck. I absolutely despise blade serrations, because I can't ever seem to get a factory edge back on them. I would recommend sending it to Spyderco or the link below.

and think if the damage you'd be doing to a smooth edge...
for Tyler34/Black Owl customs. he is the best sharpener I know all my knives have come back with better than a factory edge.
Serrated edge knives might be good in a few limited situations(like slicing bread) but overall IMO they are not for heavy users!
I cut a lot of cardboard boxes at work, and the serrations keep cutting long after the main part of the blade is dull. That's my experience, anyway.
start with a 10" wheel on your grinder.
grind off the serrations.
reapply proper edge.
done!
