Review: Great sharpening tool - I like a sharp knife but I am far from an an expert in tool sharpening. I had a couple of fairly expensive knives that I could no longer sharpen with the stones, steel rods, and ceramic sticks that I had traditionally used. I decided to invest in a diamond stone. This DMT bench stone works great and the fine/course combo has been good to restore my dull knives or tone those that were in better shape. I liked it so much that I also bought a small pocket model and and a rod by the same company for serrated blades. I am using it in the available plastic base and I think that is the way to go. I have sharpened every knife we own, my axes, all my tree and shrub trimming equipment, and I used the diamond bench stone to flatten my old sharpening stones that were grooved from use. I am glad that I bought a larger size for all the things I have sharpened. It is easy to clean with soap and water. A solid tool investment.
Review: Get a Razor Sharp Edge - I purchased a set of DMT Diamond Bench Stones, the Coarse / Extra Coarse and the Fine / Extra Fine, along with a base to hold the stones. This set allows me to put a very sharp edge on any of my knifes, axes, or chisels. I have found that the stones are easy to work with and appear to hold up very well. Sharpening in done using only a little water on the stones. I would recommend these DMT products to anyone seeking quality sharpening stones.

### ⭐⭐⭐⭐⭐ Excellent product
*by C***! on December 6, 2023*

I was able to flatten 3 Cr-V chisels that had been nicked. I used a rolling guide and was able to grind them down very quickly, clean and square. I had no problem removing material. Wide enough for plane blades.
