>>514530I've had this kit for about 5 years, with a table mount. It works well for some knives, but not for all. For example sharpening full flat grinds requires using some tape to make the sides of the blade parallel and it's still not optimal.
What I don't like about the system is that the sharpening angle is difficult to get right. My solution was to make 20 and 25 degree guides out of cardboard and I always check before sharpening..
BTW if you're creative, you can attach a cheap diamond "stone" to the wrong side of any of the stones.
My next sharpening system will be designed and built by myself.
