Does anyone else use

[Grouse]

I honestly just use a couple of diamond sharpeners. I have learned over the years on how to hold an angle to put a good edge. Good steel helps. some knives just have the worlds worst angles for keeping edges, or putting edges on. Honestly I redomend Ikea's full sized diamond oval kitchen knife sharpener for keeping an edge and a set of fishing hook diamond sharpeners (various grits) for putting a new angle on.
