Second one I buy from this company. For a while I thought I was keeping my knives sharp with the slide-through sharpeners. Someone recommended one of these to me a while back so I thought I’d give it a shot and omg what was I thinking when I thought my knives were sharp enough after using the slide-through one? After I sharpen my knives with this stone and used it, it felt like a newer sharper knife! Highly recommend the product and company.
