Check your local hardware store (don't know about the box hardware stores).
I've had them sharpened through the store and at a quilt show. Dropped 6 pairs off on Friday night and told him to do them when he had free time - I'd pick them up on Sunday. When I got them home, I wrote FABRIC and 2009, so I (and anyone else) would know they were for FABRIC ONLY and I had them sharpened in 2009.
They're wonderful when their sharp!
