The Importance of Choosing the Right Grit Grinding Wheel
When it comes to knife sharpening, choosing the right grit grinding wheel is crucial. The grit of the grinding wheel determines the level of coarseness or fineness that is applied to the blade, and can greatly affect the overall outcome of the sharpening process.
What is Grit?
Grit refers to the abrasive particles embedded in the grinding wheel. The grit size is measured by the number of mesh screens per inch, with a higher number indicating a finer grit. Smaller grit sizes, such as 100, are coarser and remove more material from the blade, while larger grit sizes, such as 1000, are finer and provide a more polished edge.
It is important to understand the different grit sizes and their corresponding applications in order to achieve the desired result when sharpening a knife.
Coarse Grits
Coarse grit grinding wheels, typically ranging from 100 to 400, are suitable for reshaping or repairing damaged blades. These wheels remove material quickly and are effective for reestablishing the proper bevel angle on the edge of the knife. They can be useful for fixing chips, nicks, or uneven edges.
However, it is important to note that using a coarse grit wheel requires skill and caution. The user must have control over the amount of material being removed to avoid damaging the blade further.
Fine Grits
Fine grit grinding wheels, starting from 1000 and going above, are designated for honing and refining the edge of the knife. These finer grit sizes help achieve a sharper and more polished edge, suitable for delicate cutting tasks requiring precision.
A fine grit grinding wheel is ideal for achieving a smooth finish on the blade and can improve the overall performance of the knife.
Proper sharpening often requires the use of both coarse and fine grit wheels. Starting with a coarse grit to reshape the blade, and then gradually moving to a finer grit for honing and finishing, can produce the best results.
Remember, the choice of grit grinding wheel should be based on the specific needs of the knife and the desired sharpening outcome. Understanding the importance of selecting the right grit will help you achieve optimal results and extend the life of your blades.

Coarse Grits (80-120)
Coarse grit grinding wheels, typically ranging from 80 to 120 grit, are used for initial grinding and shaping of the blade. These wheels are best suited for repairing badly damaged or dull knives that require a significant amount of material removal. They are also useful for reprofiling the blade or removing large chips and nicks.
Medium Grits (220-400)
Medium grit grinding wheels, in the range of 220 to 400 grit, are used for further shaping and refining the blade. These wheels are ideal for removing smaller chips and nicks, as well as for establishing a suitable bevel on the edge. They can also be used to restore moderately dull knives to a sharper state.
Fine Grits (600-1200)
Fine grit grinding wheels, typically ranging from 600 to 1200 grit, are used for honing and refining the edge of the knife. These wheels are designed to remove minimal material and produce a smooth, polished finish on the blade. They are ideal for maintaining the sharpness of a well-maintained knife or for finishing touches after using coarser grits.
It’s important to note that the best grit grinding wheel for knife sharpening depends on various factors, such as the type of knife, the level of damage or dullness, and personal preference. It’s recommended to start with a coarser grit and gradually move to finer grits for optimal results.
Overall, understanding the different grits and their uses can help you choose the right grinding wheel for your knife sharpening needs.
