As you know, keeping your knives sharp keeps you safer, since you’ll have to use less pressure to slice. A whetstone (or water stone) is how the pros keep their knives in the best shape, and this one is just $11 today, the cheapest it’s been in over 6 months. So, if you’re looking to do your own knife sharpening, get this deal before it’s gone. I would recommend watching a couple of videos on how to do it, if you’ve never tried before.
