this company has been around for quite awhile.....they used to, maybe still do, sharpen dull blades.....The original company used to owned by husband of a pioneer Longarmer, if I remember correctly...I don't know if that is still true.......
I never did business with them....easier to use JoAnn coupons or go to Harbor Freight, but if one doesn't have that as a alternative this might be a $$$$saver....
