inserted into a file guide, these are great for keeping the edges of my skis tuned. i use various grits depending on how aggressive i need to cut but much prefer these to metal files. now all my friends like to bring their skis back to my place :)
oh yeah, and they work great for lots of other sharpening tasks too. treat them right and they'll last forever.

The aligner kit that this stone works with is handy and most people should be able to put a decent edge on a knife with not much practice or know-how. This stone makes an edge good enough for average kitchen work. You do need the extra-extra fine stone to get an edge that comes close to being nicely sharp. Apparently it is expected that a diamond stone leaves a slightly rough edge. It cuts so fast and leaves tiny grooves in the beveled edge.

Update 11-5-10
I may have found a significant flaw in using diamond stones to sharpen knives and tools. I am not an expert at this, and I have not seen this mentioned anywhere else, so take it with a grain of salt.

The edge of the knives that I have been sharpening, while sharp, do not hold that sharp edge very long.

First, no matter how well you sharpen an edge, it is not perfect. The edge has little microscopic teeth on it. Similar to a saw. These `teeth' on a knife are not uniform in size, shape, and spacing, as on a saw. Nor are they rigid as on a saw. On a knife, when you cut something, these weak little teeth bend this way or that way, and the knife begins to feel dull.

My theory:
Those little bits of diamond grit on a diamond stone are, as you know, very, very hard. They cut very fast. They also cut very deep. They make deeper little grooves, on the beveled edge, than any other type of sharpening stone. These deeper grooves make larger teeth on the edge of the knife. A larger tooth is inherently weaker, and will bend more easily. Also, without going into great detail, the deeper grooves cause each little tooth to have less physical support, making them weaker still. They will bend even more easily.

No matter what you use to sharpen an edge, those little teeth are created.

if you know how to use it properly the DMT system is the best around. You have to keep in mind that you can never shave with a hunting knife. It is not the right shape or metal for that. get the angle right, and this system will give you the best play possible.
