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.

Abstract: The present disclosure provides a smoking device for drink and food. The smoking device for drink and food includes a base and a supporting net. An upper surface of the base is sunken downwards to form a combustion groove. The combustion groove is configured to accommodate fuel. A lower surface of the base is sunken upwards to form a smoke passage. The smoke passage extends upwards through a side wall of the combustion groove and is communicated to the combustion groove. At least a portion of the supporting net is inserted to a bottom of the combustion groove and is configured to support the fuel. And when the fuel in the combustion groove is ignited, the smoke passage allows smoke produced by fuel combustion in the combustion groove to pass through. The present disclosure also provides a smoking method for drink and food.
