I'm always really nervous to have anyone with my special scissors. I found a local guy (in a town of 2500) that does it for $2.50. He does such a nice job that he even fixed uneven points from a previous disaster. But overall, I think that a resharpened pair is never quite as good as originally.
When I was a senior in Highschool I got an award for being the top seamstress in home-ec. My teacher gave me a pair of Weiss thread snips, engraved with my name. They are more than just special. I even let the old guy I found do them, for the FIRST time ever.
When I worked in the OR (operating room), there was a guy who came once a month to repair and sharpen surgical instruments. I could get him to do my sewing shears.
