[SAFE KNIVE SHARPENING] Our rolling knife sharpening kit allows you to safely secure your knife by attaching the magnetic block to your knife, keeping it in place while the roller sharpens it, so you can work safely. [FULL SPECTRUP SHARPENING] Most regular knife sharpeners only sharpen the tip of the knife. Our sharpener sharpens and cuts away more of the width of the blade, making it easier to slice and chop smoothly. [ROLLING SHARPENING FUNCTION] Our unique rolling sharpener allows you to easily and effectively smooth and sharpen your knife by rolling our sharpening roller and moving your hand back and forth in a fluid motion, making your knife smooth with ease. [VARIOUS SHARPENING ANGLES] 20 and 15 degree angles for different degrees of sharpness, giving you multiple sharpness options. [DIAMOND SHARPENING DISC] Rotary grinding disc with a grit size of 46 m ensures maximum removal of your knives. [KITCHEN GIFT] This product is a must-have for any kitchen and cooking enthusiast. Perfect for chefs, hobby chefs and for chopping, slicing and cooking in the kitchen.
