Depending on your available space and your knife sharpening needs you could go for a larger unit which usually has more features or a more compact one that can save storage space but might lack certain abilities.

3. Design

Buy On Amazon

This model is ideal for converting 20-degree class knife factory edges into the Trizor XV 15 degree high-performance edge.

In the second stage, some even finer diamond abrasives shape the second bevel of the arch-shaped edge.

Finally, flexible stropping disks take care of sharpening the edge in a very efficient manner to reduce as much as possible metal removal. A microscopically smooth ultra-sharp edge is obtained as the final an the smallest bevel of the arch-shaped edge is created.
