When it comes to sharpening a knife, most people focus on the blade itself. However, the spine of the knife is often overlooked, even though it plays an important role in the overall performance of the blade. A sharp spine not only adds strength and stability to the knife, but it also enhances its functionality. In this article, we will guide you on how to sharpen a knife spine with a stone, ensuring that your knife is at its best for any cutting task.
Step 1: Choose the Right Stone
Before you begin sharpening the spine of your knife, it is crucial to select the appropriate stone. Look for a stone that is specifically designed for sharpening knives and has a rough grit. The rougher the stone, the more material it will remove, making the sharpening process faster. Additionally, ensure that the stone is large enough to comfortably accommodate the length of your knife spine.
Step 2: Prepare the Stone
Next, you need to prepare the stone before you start sharpening the knife spine. Start by soaking the stone in water for about 10 to 15 minutes. This will prevent the stone from drying out and provide a smoother surface for sharpening. Once the stone is soaked, place it on a stable surface and secure it with a non-slip mat or a damp cloth to ensure stability.
Step 3: Sharpen the Spine
Now it’s time to sharpen the spine of your knife. Hold the knife with the spine facing down and the edge facing away from you. Place the spine against the stone at an angle of about 20 degrees. Using light and even pressure, move the knife back and forth along the length of the stone, maintaining a consistent angle. Repeat this motion several times, paying attention to the entire length of the spine.
Step 4: Check the Progress
Regularly check the progress of your sharpening by running your fingers along the spine. It should feel smoother and more polished. If you notice any rough spots or inconsistencies, continue sharpening until the spine is evenly sharpened. Once you are satisfied with the result, rinse the knife and the stone to remove any metal particles and wipe them dry.
Remember, sharpening the spine of a knife requires precision and patience. Take your time, follow these steps carefully, and you will be rewarded with a knife that is not only sharp but also performs at its best.
What is a knife spine
The knife spine, also known as the back of the knife, refers to the non-cutting edge of the blade. It runs parallel to the cutting edge and is generally thicker and stronger. The spine plays an important role in the overall functionality and stability of a knife.
While the primary purpose of the spine is not to cut, it still has some practical uses. The spine can be used to apply pressure or force when needed, such as when performing tasks that require strength like splitting or batoning wood. It can also be used for tasks that require precision, such as guiding the knife while making delicate cuts. Additionally, the spine can be used for scraping or striking flint to create sparks for fire starting.
In terms of sharpening, the spine is typically not sharpened to a fine edge like the cutting edge. However, it is still important to maintain the spine’s condition. A dull or damaged spine can affect the overall balance and performance of the knife. It may cause discomfort during extended periods of use or compromise the knife’s ability to withstand heavy-duty tasks.
When using a sharpening stone, it is essential to pay attention to the spine’s condition and ensure its maintenance. While sharpening the cutting edge, it is important to be mindful of the spine and avoid unintentional damage.

Selecting the right stone
When it comes to sharpening a knife spine, selecting the right stone is crucial. There are various types of sharpening stones available in the market, each with its own advantages and characteristics.
Whetstones: Whetstones, also known as water stones, are popular among knife enthusiasts for their versatility. They come in different grit levels, ranging from coarse to fine, allowing you to choose the level of sharpness you desire. Whetstones can be made of natural materials like novaculite or synthetic materials like aluminum oxide or silicon carbide.
Diamond stones: Diamond stones are known for their durability and aggressive cutting action. They are made by embedding small diamond particles onto the sharpening surface. Diamond stones are ideal for shaping and re-profiling knife spines due to their ability to remove metal quickly.
Ceramic stones: Ceramic stones are excellent for achieving a polished edge on knife spines. They are made from a combination of ceramic and synthetic materials. Ceramic stones provide a fine finish and are great for maintaining a sharp edge on already sharpened knives.
Oil stones: Oil stones, as the name suggests, require the use of oil as a lubricant. They are typically made of aluminum oxide or silicon carbide and come in various grit levels. Oil stones are known for their durability and ability to remove metal efficiently.
When selecting a sharpening stone, consider the type of knife you have and the level of sharpening required. Coarser stones are suitable for repairing and reshaping damaged spines, while finer stones are better for fine-tuning and polishing already sharpened spines.
Remember, regardless of the type of stone you choose, it’s essential to keep it clean and properly maintained to ensure optimal performance.
Preparing the knife
Before you begin sharpening the knife spine, it is essential to prepare the knife properly. Here are the steps to follow:
Clean the knife
Make sure the knife is clean and free from any debris or dirt. Use a damp cloth or sponge to wipe down the blade and remove any residue.
Remove the handle (if necessary)
If your knife has a removable handle, take it off to expose the spine completely. This will make it easier to sharpen the spine without any hindrance.
Note: Not all knives have removable handles. If your knife doesn’t have one or it cannot be removed, you can still sharpen the spine with the handle intact, but it might require more precision and caution.
Protect the edge of the blade
Before proceeding with sharpening the spine, it’s important to protect the cutting edge of the blade. You can do this by covering the edge with a piece of folded cloth or tape.
Tip: Use a cloth or tape that is thick enough to provide sufficient protection to the edge but thin enough to allow you to access the spine easily.
