I couldn’t wait to get this sharpening stone to sharpen my knives. I wasn’t disappointed! This made my dull knives sharp sharp sharp. The instructions were clear. The stone is durable as I’ve used it on several knives. It still works great!! I like the rubber base so you can sharpen with confidence that the stone won’t slip on you!

I recently purchased this sharpening hone after realizing my kitchen knives were barely cutting through tomatoes anymore. I didn’t want to spend a fortune or send them out to be professionally sharpened, so I figured I’d give this a shot—and I’m honestly blown away by the results. The hone feels sturdy and well-made, and the grit (I went with a medium/fine combo) was just right for touching up all my everyday knives. Within minutes, I had my chef’s knife slicing paper like it was butter. It also worked well on my pocketknife and even a dull chisel I had lying around. I appreciate that it doesn’t require oil—just a little water and it’s good to go. Cleaning it was easy, and it hasn’t worn down or dished at all yet after multiple uses. For the price, the performance is seriously impressive. If you’re on the fence or new to sharpening, this is a great entry-level hone that still delivers pro-level results. I’d recommend watching a quick video on sharpening technique to avoid damaging your edge—once you get the hang of it, it’s incredibly satisfying.
