If your going to sharpen your lawnmower blade on your own Ken, you should also invest in one of these....

The harbor freight vice and grinder that i linked you to work very well for the money, I do a decent amount of metal work.. These two items get used quite regularly at my house. For the money you can't go wrong... Are they as "high quality" as other options... No, but they do the job just fine, and cost a fraction of what the premium product does...
