Review on DMT OD2K Dia Sharp Mini Hone Diamond by Khiam Burton

no signature stones. This mini diamond dust sharpening kit has become my favorite for knives including ceramic knives. Use all three or at least medium and fine grit and water to lubricate/flush. They work great. They are not suitable for tight spaces like tool bits. I also have some small 1/4-width diamond "files" that are better suited for small carbide tools. I haven't used them long enough to know how long it will take for the diamond dust to wear off. You don't need a lot of strength. I suspect that if you use a lot of force by bending the sheet metal that the diamonds are embedded in, you could damage the tool. That's why I only give them 4 stars.
