I'm frustrated to the point that I just joined this forum to get your advice: I have decent - or what i consider decent - knives. They were wedding gifts - perhaps a $200 set, for 5 knives. They don't hold their edge. I purchased a $150 knife sharpener and have used it for almost a year - Chef's Choice M130 or similar. The knives are sharp for what feels like 5 minutes. I use a steel. Can someone offer advice on how to rescue my knives, and whether my decision to buy and use a high-end home sharpener is a good one! Help help help. Thanks all.
