Input:
A month ago, I had a drawer full of dull knives. I then heard this knife sharpener recommended on an America's Test Kitchen podcast I was surprised to find that it was so inexpensive. I ordered it and used it right away. It is very easy to use, just follow the printed instructions on the packaging. I was skeptical that something so inexpensive could make such a difference but I have been using my newly sharpened knives for about 3 weeks and haven't had to sharpen them again. As someone who uses knives many times a day, it is great to have a safe, easy way to sharpen knives!
