Abstract: A storage box includes a base having a bottom portion with inner and outer surfaces, and a peripheral wall surrounding the bottom portion to form a storage space with the inner surface. The outer surface has a placing slot and a knife sharpener fixing portion adjacent thereto. When the user places a knife sharpener in the storage space and closes a covering plate, the whole storage box is portable. The knife is sharpened when the covering plate is detached and embedded in the placing slot while the bottom portion is orientated upward, and the knife sharpener is disposed on the knife sharpener fixing portion. The user moves a knife back and forth between the knife sharpener by one hand and puts the other hand beside the covering plate to avoid being gashed by the knife in the knife sharpening process, thereby achieving protection purpose.

Abstract: A device for sharpening a knife. The device includes an enclosure, first and second grinding strips, first and second grinding strip holders, and first, second, third and fourth pendulum rods. Each of the first and second grinding strip holders have a lower section. The first grinding strip holder holds the first grinding strip and the second grinding strip holder holds the second grinding strip. The first and second grinding strip holders are movably arranged next to each another in the enclosure so that the first and second grinding strips intersect to form a movable sharpening slot having a V-shape. The first and second pendulum rods are hinged to the first grinding strip holder at the lower section via a lower joint. The third and forth pendulum rods are hinged to the second grinding strip holder at the lower section via a lower joint.

Abstract: The device includes a holder for retaining the knife blade in a fixed position with the cutting edge accessible from above. One end of a moveable abrasive part is situated above the cutting edge. The other end of the abrasive part is supported by a retaining member and sets the angle of the abrasive part relative to the knife blade when the abrasive surface contacts the cutting edge. The cutting edge is sharpened as the abrasive part in contact with the cutting edge is moved along the length of the knife blade. The abrasive part may be a stone or a rod with an abrasive surface. The retaining part may have a ring shape or take the form of a clamp which attaches to the stone in different positions.
