Abstract

A knife block may include a block body with a recessed portion and a block insert positioned at least partially within the recessed portion. The block insert may include a first knife slot and a second knife slot. The knife block may include a first knife sharpener coupled to the block insert, where the first knife slot is sized such that a first knife is sharpened by the first knife sharpener each time the first knife is removed from the first knife slot, and a second knife sharpener coupled to the block insert, where the second knife slot is sized such that a second knife is sharpened by the second knife sharpener each time the second knife is removed from the second knife slot. The knife block may include a first knife storage slot and a second knife storage slot.

9. The knife block set according to claim 1, further comprising a second knife storage slot extending through the second surface of the block body, wherein the second knife storage slot does not have a second knife sharpener aligned with the second knife storage slot.

10. The knife block set according to claim 1, wherein the block insert is mounted in the recessed portion;

and

wherein the first knife sharpener is removably attached to the block insert.

11. The knife block set according to claim 1, further comprising first indicia on the first surface of the block body, the first indicia associated with a first opening and relating to one or more knife characteristics.

12. A cutlery set comprising:

a knife block having a block body and a first storage slot extending through a face of the block body;

a removable block insert positioned at least partially within the block body, the block insert comprising a top side, an opposing bottom side, and at least a first knife storage slot extending through the removable block insert;

a removable cap comprising a first cavity, wherein the removable cap is positioned along the bottom side of the block insert between the face of the block body and the block insert;

at least a first knife sharpener positioned at least partially between the block insert and the removable cap and aligned with the first storage slot and the first knife storage slot, the first knife sharpener including two sharpening elements that form a V-shape and have a sharpener angle; and

a first knife having a first blade and a first handle, the first blade having a knife edge with a blade angle, wherein the first storage slot is sized to receive the first blade, and wherein the first blade is sharpened by the first knife sharpener each time the first blade is inserted into the first storage slot;

wherein the sharpener angle is greater than the blade angle, and the first knife sharpener contacts and sharpens the knife edge of the first blade.

13. The cutlery set according to claim 12, further comprising a second storage slot, wherein the first storage slot has at least one size characteristic that is different from the second storage slot.

14. The cutlery set according to claim 13, wherein the at least one size characteristic is one or more of a length into, a width across, or a height along the block body.

15. The cutlery set according to claim 13, wherein the first storage slot is oriented at a first angle relative to a horizontal reference and the second storage slot is oriented at a second angle relative to the horizontal reference.

16. The cutlery set according to claim 15, wherein the first and second angles are the same and between 40 degrees and 55 degrees relative to the horizontal reference.

17. The cutlery set according to claim 16, wherein the first and second angles are between 42 degrees and 48 degrees relative to the horizontal reference.

18. The cutlery set according to claim 12, further comprising a second knife with a second blade, wherein the first blade has at least one size characteristic that is different than the second blade.

19. The cutlery set according to claim 18, wherein the at least one size characteristic is one or more of a blade length, a blade width, or a blade height.
