[QUOTE=grammasharon;7958697]I tried several different packages from Harbor Freight and could not get any of them to work. I buy all my blades on Amazon for very reasonable prices and so far after 3 different shipments and 3 different distributors have not had an issue with any of them. In fact this last pack I got just don't seem to get dull. Wish I would have paid closer attention to where I ordered them from.[/QUOTE]
If you go to Amazon and look at your previous orders, you can find where you ordered them from! If the blades are as good as you say, please share the source when you find it! I agree about Harbor Freight - some people seem to get luck, but not me.
