The angle of the guides can be tweaked according to the type of blade requiring enhancement, and this ability makes the sharpener a lot flexible and compatible with a wide range of knives.

The drawbacks of the product revolve around its 1-year warranty. Although the manufacturers assure fixing the usual wear-and-tear that occur over the course of 12 months, this cost doesn’t cover the damage of abrasives.
