What is the best grit of sandpaper for sharpening knives?
Using sandpaper, you can sharpen a blade between 600 and 800 grit. By creating a bevel, you will be able to sharpen the edge later. Even so, if you want a clean finish on your knives’ blades, you have a lot more to do.
I think this is when we need to consider the sharpening technique as well as the size of our sandpaper. With the larger grit sandpaper sheets the blade will gain a mirror-like shine and a polished look while the smaller grit sandpaper sheets will sharpen the edges and the blade will form a sharpened edge.

What Grit Sandpaper To Use for Knife Sharpening?
This is the right size of sandpaper for sharpening knives: 600 grit. If you wish to repair the knife before beginning the sharpening process, you may wish to do so with a lower grit before beginning the sharpening process.
Let’s take a look at the grit system for sandpaper, which will help you fully understand how it works. There is a listing of the different types of sandpaper, as well as their most common uses.
Coarse 100-400
- Be sure to remove materials such as metal and wood as quickly as possible.
- Knife blades should be reshaped.
- The knife-edge needs to be prepared by removing large chips and scratches.
- Snapped points should be restored.
- Double-bevel the edge.
- Bring back a dull edge.
- The stone flattens.
Medium 400-700
- Make sure you remove enough metal and scratches for fine edges.
- A coarse grit is used to create a fine edge.
- Blades that are dull can be restored.
- Determine the bevel angle.
- Creating a fine edge by sharpening blades.
Fine 800-1200
- Blades that are dull can be retouched.
- A factory edge will be created with the previously calculated bevel angle.
Extra-Fine 2000+
- Blades and steel are polished.
- Shine and sharpen the edges.
- Sharpen straight razors to a mirror finish.
Number of Grits in Sandpaper
Generally speaking, grit number refers to the size of the abrasive coating on the surface of sandpaper. This is determined by the size of the grains within the surface.
A higher number indicates a finer abrasive, whereas a lower number indicates a coarser abrasive.
In addition to the blade’s condition, the grit size you should use is also determined by the condition of the blade’s edge. In accordance with the chart above, coarser sandpaper, which ranges between 100-400 grit, can be used to reshape the blade by removing chips and scratches.
Meanwhile, if you wish to polish a knife that has been sharpened, you might want to use sandpaper with a high grit rating. Make sure to pick the correct size according to the knife.
Here’s how to use sandpaper more easily:
When sharpening a knife, use the lower grits and, afterward, use the higher grits to smooth the blade and remove impurities. Using both low and high grits will effectively sharpen knives.
Why Do Grit Numbers Matter?
It is important to know what the grit number can do for you. The grit size of sandpaper is appropriate for different purposes, from removing scratches to sharpening.
Let’s look at a few examples of how each grit in sandpaper works.
To polish the sharpening, you can use 1200 or 1000 sandpaper after you sharpen a knife with coarse paper.
It is important to know that extremely fine grits can damage the edge of the blades and burn the blades. You can also use a block to support the blades.
You can also give a knife a razor edge by sharpening it with 800 grit and buffing it on the buffing wheel briefly. Kitchen knives, including chef’s knives and paring knives, can be cleaned in less than a minute using this method.
To finish sharpening the slack belt or leather belt, some people recommend going with a lower number, such as 600 then a strop or 400 grit sandpaper.
Then, to finish it off, a quick wipe down with a whetstone will give you the necessary finishing edge.
The 220 grit is another commonly used sandpaper when sharpening knives. During the first stage of sharpening, it is the safest for bevels. Also, you may use a buffing wheel in conjunction with the sharpening stone if desired.
Lastly, you can also apply the 100 grit paper over a sheet of plate glass to prevent damaging scratches on the surface of the blade. When compared to the old sharpening stones that were used many years ago, glass is the ideal flat surface for sharpening. You can therefore begin to increase the grit size of the sandpaper until you get the sharp edge you desire.
In Sandpaper, the number of grits you need to use
Sandpaper with a grit of 600 and higher is ideal for sharpening knives. Preparing the blade with the lowest 100 grit will prevent damage to the steel or metal material.
Scratches and impurities can also be removed with these. Once you have a sharpened edge, apply higher grits and hand sand it to polish.
The Minimum Size of a Grit in Sandpaper
Sandpaper of high grit smoothes the blade while sandpaper of lower grit sharpens it.
In reality, you can purchase sandpaper with grits as low as 40 to 80. This grit is intended to repair chipped edges or re-establish initial bevels.
Grit in Sandpaper: A Texture Analysis
Sandpaper has a different texture depending on its rating. Here’s how it’s classified:
The texture is coarse, ranging from 200 to 600.
Medium texture, between 600 and 1000.
Texture ranging from 1000 to 600.
From 6000+, extra fine texture.
How Does Texture Affect the Experience?
Material such as metal or wood reacts differently to sandpaper depending on the texture.
You can increase the roughness of an edge by using coarse textures, which allow you to symmetrically shape both sides of a bevel.
The first stage of the blade sharpening process first refines and hones the primary bevel shape using medium grit sandpaper.
Sharpening the steel blade of the knife is achieved by polishing and rubbing the blade with fine (2000 grit) and ultra-fine (6000 grit) textures.
Can You Sharpen a Knife With Sandpaper?
If you use the right grit size and technique, you can sharpen a knife with sandpaper.
There is no reason to use a sharpening stone or tiles to sharpen your knives. Although the above methods work great, there is a new and better way to sharpen knives by yourself using sandpaper that is much simpler and more cost effective.
To sharpen your pencils, the mouse pad trick is the recommended method to follow. Here is how to do it.
You’ll need 600 grit sandpaper and a mouse pad from an auto supply store.
Whether you use wet or dry sandpaper, choose mylar-backed sandpaper that will adhere to itself. Furthermore, pick up 1200 grit sandpaper sheets.
Trim the edges of the mouse pad with the sandpaper attached. We will make you your own DIY knife sharpening kit, which means you won’t have to buy a cheap stone or sharpening tile.
Put one side of the mouse pad with 600 grit sandpaper and the other side with 1200 grit.
When using this knife sharpening system, you have to strop the knife as you sharpen it. You will get better results by using a stroke that trails the edge. In addition, sharpening should not be initiated by the edge, but rather the spine.
A simple angle can be established. The knife should rest flat over the pad so that its edge points the way you are working. You should then lift the spine gently as you pull the knife toward you. As if you were cutting a thin slice with the knife.
Allow the edge to bite into the sandpaper without stopping lifting. Stropping is how you do it.
Push the knife gently away from your body and start pressing down. Start by moving the knife from heel to tip starting with the spine.
After reaching the end, stop and lift the blade. Otherwise, the edge will be ruined.
Continue to stroke the knife in the opposite direction by turning it to the other side. As you pull the spine towards you, it should be with the edge away from you. Maintain the same angle you used earlier.
With the 1200 sandpaper sheets, polish the other side of the mouse pad.
And that’s how you can build a DIY knife sharpening kit that you can use without spending a ton of money on. We will now discuss some tips that will help you sharpen knives with sandpaper more effectively.
How to Sharpen Knives Using Sandpaper
It is a good idea to use sandpaper sheets rather than stones for sharpening knives because sandpaper sheets are more consistent in quality and you only have to spend a few minutes sharpening them. Additionally, it won’t damage the blades of knives at all, unlike a sharpening stone, which could leave a mark on the blades.
A fantastic way of sharpening knives is by using the Mousepad Trick. By using this tool, you can sharpen blades at a consistent angle, making it possible to sharpen both sides of the blade at the same time.
The best part is that you can make your own knife sharpening set by using these tools which will cost you less and can be carried wherever you go. You can do it without any difficulty and it is light and convenient.
You can easily sharpen knives using sandpaper if you don’t have a polishing wheel. However, it has been suggested by some that diamond stones are the most efficient way to sharpen knives.
However, this does not mean you cannot use both sharpeners at the same time. Wet and dry sandpaper can be used over a flat surface to sharpen the edge. Otherwise, you could finish the sharpening with a sharpening steel or stone.
It is also possible to glue or spray adhesive over the surface area of a flat board and attach sandpaper to it. When sharpening knives with this, you will be able to sharpen them more quickly than using sharpening stones.
Questions & Answers
How Do You Smooth the Knife Spine With Sandpaper?
Sand the knife spine with high grit sandpaper, normally 600 to 1200 grits. Almost all knives can be repaired this way.
Sandpaper gets dull over time?
As time passes, the sandpaper becomes dull. It is, however, because of the frequent sharpening of knives that the sandpaper becomes dull over time.
When the abrasive side of the sandpaper wears down and is no longer able to smooth or sharpen a flat surface, you should change the dull sandpaper.
Sandpaper with a grit of 7000 is used for what?
Primer, putty, and filler, among others, can all be sanded with a 7000-grit sandpaper. Primer, putty, and filler, among others, can all be sanded wet or dry.
What Is the Use of 120 Grit Sandpaper?
It is best to use sandpaper with a grit between 120 and 220 for removing large amounts of material quickly, repairing chips on edges, and removing scratches.
Sandpaper of this type can be used to remove imperfections from kitchen knives. A knife’s steel blade has to be ground down first before it can be sharpened.
What is better, higher grit?
Sandpapers with a higher grit will have finer abrasives. Sandpapers of high grit are therefore perfect for polishing and smoothing surfaces.
Alternatively, paper of a lower grit is coarser and abrasive and scrapes faster. A knife’s blade must be prepared and sharpened both before it can be used.
Conclusion
If you want to sharpen your knife, a 600-grit sandpaper is ideal, but for polishing your work, grits lower and higher are preferred. This is why it’s best to use all grit sizes together, rather than choosing one at a time.
It is possible to give your knives a new edge just by using a bit of sandpaper correctly without having to buy expensive tools. Due to this reason, you will not only enjoy the benefits of this method, you will also save a significant amount of money.
