This is a good company and they have good blades, not seconds. I have traded with Mr. L P Sharp for many years and now I think that he has sold his name to a company . I put my old blades in an empty blade package and when I get enough I mail them in and get new blades in return for a small amount. Just check out the new blade cost at a shop and you will see how much you can save. But you need to keep your used blades separate by brand name.
