Before I bought myself a knife sharpener, I had to take my knives to my local butchery to get them sharpened. He did a pretty good job, but I needed to find an alternative. I have more than 15 knives; it was becoming expensive not to mention time consuming.
I did go shopping and found myself an amazing electric knife sharpener. It now takes me a minute or less to sharpen a knife and, even better, I use and sharpen the knife I want or need to use.
