Question 1

Does this item use stone or diamond abrasive wheels? The exact same model number sells for $179, and that is listed as using diamond.

Accepted Answer

Working Left to Right, the first stage is a medium coarse diamond disc to realign and set the angle of the blade. (note use this stage sparingly or on a very dull or damaged knife). 
The second or middle stage is a fine diamond disc which will put the final angle on the edge of the blade. This stage you will use each time you "touch up" your knife.
The third or right side stage is a polishing stage with fiber ( I believe a diamond impregnated) discs. Use this stage to remove the burr created by the other stages and to polish the edge of the blade for a keen edge. This stage can be used for serrated edge sharpening also.
Use stage 1 and stage 2nd to create a burr. Then the 3rd stage to polish the edge.
There is a small lever on the back lower part of the sharpener. This is used to clean any debris from the 3rd stage buffing wheels. I have owned mine 10 years and never used this feature.
My recent purchase (March 2023) of the Trizor 15XV was for my son.
We are a outdoors family and process our own fish and game, in season they get well used.

Question 2

Anyone with experience converting a 22-degree knife edge (like a Cuisinart stainless steel knife) to 15 degree using this machine? How was the result?

Accepted Answer

All I can tell you is that my son purchased this for our household cutlery. He works in the food industry and when he took it to work to sharpen all the knives, the owner was so impressed ge bought from him.

Question 3

Manufacture lists two model 15xv; which one is sold by amazon as their asin no. b07h4gnstn?

Accepted Answer

I'm very happy with this little gizmo and can attest to the fact that it does a GREAT job... takes up very little space on the counter, too, and although I planned to store it until needed.  What I found, though, is that I use it more frequently for constantly sharp knives... so easy!  (I keep it on the counter now,)

Question 4
