I've used Raleigh Saw for years, it will be a trip for you, but you will not be dissapointed: Raleigh Saw Co. 5805 Departure Dr 919-832-2248
Gresham Lake area north on Capital Blvd just beyond I 540. Call and they will give you good directions. They will even test your blades prior to sharpening, and if damaged or warped will not sharpen, just return them to you. It's not often that you find that kind of honesty and they ingrave each blade with a number so they can follow each blade in your account every time you take it in. Make a blade "board" with a handle and bolt to hold your blades put your name on in permanet pen and you have the best way to transport blades to and from. It usually takes about a week to get them back.:lol:
