Have you ever wondered how the grinding process works? What exactly does an expert knife-sharpening service like Sharp-End do to bring your knife edge back to its razor sharp condition?

Grinding is a unique process that is more intensive than honing or polishing. When a blade is sharpened for the first time or has been damaged or misused the grinding process removes significant portions of uneven metal from the blade surface. Knives that are properly maintained and cared for will need less frequent grinding and will last for much longer than knives that are neglected.

Technically speaking, blades made of harder steels take sharper edges, but are generally more brittle and prone to chipping.Softer steels are tougher and are used for tools like cleavers which must be tough but do not require a sharp edge.

At Sharp-End, our highly skilled technicians will choose the most appropriate grind for each blade, depending on how it is used and the material that the blade is made of. Many knife manufacturers offer various models of the same knife with different grinds on the blade. An expert sharpener can even reshape the blade to the owner’s custom specifications to achieve different blade properties. However, before changing the grind, it’s important to understand that some grinds are easier to maintain than others. Others can withstand constant use and will provide a better shape over the life of the blade if it will require repeated sharpening. Not sure which shape is best for your blades? Feel free to contact us for more information.

The two most important factors in knife grinding are edge angle and included angle. The edge angle is measured between the surface of the blade edge along an invisible line that runs from the point of the cutting edge to the center of the back edge. The included angle is the sum of all the edge angles. Generally, the smaller the included angle, the sharper (but easier to damage) the blade will be.
