This invention relates to knives, and in particular to systems, devices, and methods for providing different types of sharpeners for knives with an angle gauge to determine which knife sharpener to use for individual knives.
Over time there is a need to sharpen blades on knives. It is generally not practical for consumers to use sharpening stones, so the consumers generally look to sharpening devices. Over the years many types of knife sharpening devices have been proposed. See for example, U.S. Pat. No. 3,332,173 to McMaster et al.; U.S. Pat. No. 8,585,462 to Jensen; U.S. Pat. No. 8,590,427 to Murphy et al.; U.S. Pat. No. 8,678,882 to Huber et al.; U.S. Pat. No. 9,168,627 to Elek et al.; U.S. Pat. No. 9,333,613 to Friel, Sr. et al. and U.S. Pat. No. 10,220,490 to Wu.
However, these devices do not solve all the problems encountered with persons wishing to sharpen different sizes and types of knives. For example, users have difficulty using prior art knife sharpeners since it is unclear what angle sharpening sizes should be used for each knife.
In addition, knife sharpeners are usually limited to only having a few different size knife sharpeners and do not cover most of the different knife blade angles. Still furthermore, more sharpeners only have one type of sharpener such as only having ceramic wheels and not other types of sharpeners.
Thus, the need exists for solutions to the above problems with the prior art.
A primary objective of the present invention is to provide systems, devices, and methods for providing different types of sharpeners for knives with an angle gauge to determine which knife sharpener to use for individual knives.
A secondary objective of the present invention is to provide systems, devices, and methods for providing ceramic wheel knife sharpeners with diamond coated metal wheel sharpener and tungsten rod knife sharpeners in a single knife sharpener.
A third objective of the present invention is to provide systems, devices, and methods for providing a knife sharpener with a removal knife blade gauge that allows users to determine the desired knife blade angle to be used.
An embodiment of the knife sharpening device, can include an elongated frame, a plurality of different knife angle size sharpeners mounted along the elongated frame, and a removable knife gauge mounted to the elongated frame, wherein the removable knife gauge is removed so that a knife blade angle is determined by the knife gauge.
The plurality of knife blade sharpeners can include a plurality of honing sharpeners. The honing sharpeners can include a plurality of ceramic wheels
The plurality of knife blade sharpeners can include a plurality of edge shaving sharpeners. The edge shaving sharpeners can include a plurality of diamond coated metal wheels.

The different knife angle size sharpeners can include a plurality of honing sharpeners to straighten the blade edges, a plurality of edge shaving and straightening sharpeners for the blade edges, and a plurality of edge shaving and new edge creating sharpeners for the blade edges.
The plurality of honing wheels can include ceramic wheels.
The plurality of edge shaving and straightening sharpeners can include diamond coated metal wheels.
The plurality of edge shaving and new edge creating sharpeners can include tungsten rods.
The removable angle gauge can include a metal plate having a plurality of grooves with different angles for measuring different knife blade angles. The different angles can be between approximately 13 degrees to approximately 21 degrees.
The grooves can include separate different angles of approximately 13 degrees, approximately 14 degrees, approximately 15 degrees, approximately 16 degrees, approximately 17 degrees, approximately 18 degrees, approximately 19 degrees, approximately 20 degrees and approximately 21 degrees.
A method for determining blade angles for selecting a blade sharpener, can include the steps of: providing knife blade sharpeners that includes: a plurality of honing sharpeners, a plurality of edge shaving sharpeners and a plurality of new edge creating sharpeners, providing a blade angle gauge having a plurality of grooves for measuring blade angle sizes, determining a size of a knife blade with the blade angle gauge, and sliding the knife blade back in forth in a selected one of the knife blade sharpeners until a desired sharpened blade edge is achieved.
The step of providing the blade angle gauge can include the step of providing the blade angle gauge with a plurality of grooves for blade angles between approximately 13 degrees to approximately 21 degrees.
The step of providing the blade sharpeners can include the steps of providing ceramic wheels as the honing sharpeners, providing diamond coated metal wheels as the edge shaving sharpeners, and providing tungsten rods as the new edge creating sharpeners.
