It’s a good indication that you need to sharpen your knives when you dirty 5 of them in one sitting trying to cut a single tomato! There is an easy fix for the frustration that results from this though, and it only costs 5 bucks! I picked this knife sharpener up at Walmart and it works wonders.
Once you’ve revived your knives, you will want to get in the habit of using your sharpening steel. I didn’t even know what this thing was until I watched a Julia Child episode a few years ago and she demonstrated how to use it. My knives were dull back then and I remember pulling the sharpening steel out and working it for an enitre hour, not seeing much improvement. Why? Because a sharpening steel is used to maintain not restore! And I haven’t used the thing since. But now that my knives are sharp, I am going to keep them that way!
