Review on 💎 Diamond Coated Crystal Sharpener: The Ultimate Multi-Purpose Tool for Precision Sharpening by Brett Slater

I used to have a glass filter but it was big, bulky and difficult to use. I needed a new one so I decided to give it a try. Arrived quickly and started using immediately. There are no instructions for the product. So I used it the same as the previous one. It worked much better, faster and more evenly. Very fast. I was impressed with the speed with which he placed the chip and how I was able to use both the flat and rounded sides. I am happy with my purchase. It does what I need and saves me from throwing away my old drinking glasses.
