Blade sharpening device

Abstract

The invention provides a blade sharpening device designed for sharpening a blade for a uniform sharpening of the edge thereof. Generally, the blade sharpening device includes a base, a guide, a carriage, and a blade holder. The blade holder secures the blade while being sharpened. The blade holder is connected to the guide which is movable relative to the base. The base includes a material that receives an impression of a blade to define a blade contour and a grinding medium which provides an abrasive surface. The carriage interacts with the guide to define a sharpening path substantially aligning with the blade contour. The carriage and the guide direct the movement of the abrasive surface along the contour of the blade for a uniform sharpening of the edge thereof.

AI Technical Summary

Benefits of technology

[0020]An embodiment of the present invention preserves the advantages of prior blade sharpening devices. In addition, it provides new advantages not found in currently available blade sharpening devices and overcomes many disadvantages of such currently available blade sharpening devices.

[0026]It is therefore an object of the blade sharpening device to provide consistency in both a contour and an edge of the blade during sharpening.

Problems solved by technology

The main purpose of the grinding medium is to use something harder than the metal of the blade and grind the blade against it, manually, with little assistance to the user in controlling the angle of the blade.

The drawback to using a grinding medium without further assistance is the skill required by the user is an art that is difficult to obtain for ordinary users of the grinding medium.

Attempting to sharpen a blade without the proper technique can result in permanent damage of the blade.

Another drawback to this method of sharpening is the time and effort involved in sharpening blades.

The drawbacks are that the guides do not make use of the entire stone, the guide degrades during the sharpening process, and the path of the blade is still directed by the user which requires sufficient skill.

In addition, it has many of the drawbacks discussed in the grinding medium above.

However, it has similar drawbacks featured in the guides and the grinding medium above.

The drawback to this system is the rods are in a predetermined angle that the user will find difficult to adjust.

It also has all the drawbacks of the previously mentioned rod-guided systems.

The drawback of these gadgets is that sometimes they damage the blade.

In addition, the overall quality of the sharpened blade is low.

The belt sander or the stones are aggressive grinding mediums that can damage a blade in an unskilled user.

These machines sometimes fail to produces a sharp edge on the blade and can scratch the sides of the blade.

Not all of them consistently create a razor edge on a blade.

Consequently, these devices still require some a skilled user for operation.

It is an expensive tool designed for professional use.

The jigs are sold separately, making it even more expensive.
