Knife sharpener and knife sharpening device

Abstract

The present disclosure provides a knife sharpener. The knife sharpener includes a hand shank and a sharpening member. Mounting portions are arranged at two ends of the hand shank. An outer diameter of each of the mounting portions is greater than an outer diameter of the hand shank. The sharpening member is connected to the mounting portions, so that the sharpening member and the hand shank rotate axially. During use, the knife sharpener is put on an operating platform, such as the ground or a tabletop, and the knife is fixed on one side of the knife sharpener. The knife can tilt towards an end portion of the knife sharpener to make a cutting edge lean against the sharpening member. During sharpening, a user pushes the hand shank back and forth with the palm, so that the knife sharpener moves back and forth relative to the knife.
