I am picking up a Foley 450 Dedicated Blade Sharpener in a couple of days. My yellow pages ad info is due by mid July for next years listing. My question is, should I advertise that "We do blade sharpening" and try to generate some revenue to pay for itself? Does anyone sharpen for others? I couldn't find anyone around here that sharpens blades properly. My local guy can't even sharpen my chainsaw blades right. heres a picture.
