I have had a wonderful set of Henkels carbon steel knives for years and years. I really like using them, but they dull very quickly and I'm always having to bug my husband to sharpen them. As you all know it's quite difficult to use a dull knife. Anyhow, I've been thinking that perhaps an electric knife sharpener, to keep on the counter next to the knives, might be a handy tool, but am wondering if they are worth the price and do a good job. Has anyone here had experience with these sharpeners and, if so, any pro/con recommendations? Thanks everyone.
