Excellent product for setting (or re-setting) an edge

Very nice to have the ability to easily adjust a factory edge bevel that's too thick for my preferences, and doesn't take hours to do. Make sure to use light pressure, and let the stone do the cutting. The thing with DMT stones is that they take forever to wear out. There will be an initial loss of cutting aggression after it has been used for a little while, because the diamond dust that's sitting right on the very top (that cuts so deeply) will embed in steel and rip off of the stone, but this is kind of like breaking in a gun with a few hundred rounds. Once those really sharp little teeth have been removed, the stone will cut slightly more slowly but with a MUCH more consistent finish for years and years. I sharpen professionally and have worn out exactly one DMT stone in eight years on hundreds of knives.

Using up the diamond sharpeners

I am the neighborhood knife sharpener. I have worn out two of the coarse whetstones and several intermediate grits. I have not used a natural stone since the late 1980's. Reshaping a Katana did in the latest stone, 28-1/2" of folded steel with an edge at Rockwell 63. My everyday carry folder is made of ZDP189 at a Rockwell of 67 which just skids on top of natural whetstones without cutting. Yes, I am totally a fan of DMT sharpening equipment, some other brands also function well but DMT holds consistent surface smoothness and even cutting that is a small step above.

I use this on my DMT Aligner - it works great on knives

This isn't listed as a stone for the DMT Aligner, but it fits exactly the same as their other Aligner stones. Not for regular use on knives, but when you want to grind of some major amount of steel this really works well. This is a great stone for major knife repairs & re-profiling.
