A combat knife is an essential tool for anyone in the military or law enforcement. However, over time, the blade can become dull and lose its effectiveness. Sharpening a combat knife is a skill that every soldier should learn, as a sharp knife is safer and more efficient to use.
One of the most effective ways to sharpen a combat knife is by using a wet stone. Wet stones, also known as sharpening stones or whetstones, are specially designed to remove metal from the blade and create a sharp edge. While there are many different types of wet stones available, the basic principles of sharpening remain the same.
Before you begin sharpening your combat knife, it’s important to gather the necessary materials. You will need a wet stone, water, and a towel. The wet stone should be soaked in water for about 10 minutes before use, to ensure that it’s properly lubricated. Once the wet stone is ready, place it on a stable surface, such as a table or countertop.
Next, hold the combat knife firmly in one hand, with the blade facing away from you. Place the edge of the knife against the wet stone at a 20-degree angle. This angle will allow you to create a sharp edge without removing too much metal from the blade. Using light pressure, push the blade down and across the wet stone, moving it in a sweeping motion from heel to tip.
Repeat this motion several times, alternating sides of the blade each time. Keep the blade lubricated by periodically dipping it in water or sprinkling water on the wet stone. It’s important to maintain a consistent angle and pressure throughout the sharpening process, to ensure an even edge.
Once you are satisfied with the sharpness of the blade, rinse the combat knife under running water to remove any metal shavings. Dry it thoroughly with a towel, being careful to avoid the newly sharpened edge. Test the sharpness of the blade by carefully running your thumb along the edge, applying light pressure. If the blade easily catches on your skin, it’s sharp and ready to use.
Remember, sharpening a combat knife with a wet stone takes practice and patience. Don’t rush the process, as it’s better to sharpen the blade slowly and correctly than to rush and risk damaging the knife. With some practice, you’ll be able to keep your combat knife sharp and ready for any challenge.
Preparation for sharpening a combat knife
Before beginning the process of sharpening your combat knife with a wet stone, it is important to properly prepare both your knife and your workspace. Taking the time to complete these steps will ensure that you achieve the best possible results and maintain the longevity of your knife.
First and foremost, make sure that your combat knife is clean and free from any dirt, debris, or rust. If necessary, use warm water and a mild detergent to gently clean the blade. Dry the knife thoroughly after cleaning to prevent any moisture from interfering with the sharpening process.
Next, find a sturdy surface to use as your sharpening station. It’s essential that the surface is stable and won’t move around while you’re sharpening. You may want to lay down a towel or mat to protect the surface from any scratches or damage.
Gather all the necessary materials for sharpening your combat knife, including a wet stone, water, and a lubricant such as honing oil or water. The wet stone should be soaked in water for about 10-15 minutes before using it to sharpen your knife. This will ensure that the stone is properly lubricated and ready for use.
Once you have completed these preparation steps, you are ready to begin sharpening your combat knife. By taking the time to prepare your knife and workspace, you can ensure that the sharpening process goes smoothly and effectively.
Choosing the right wet stone
When it comes to sharpening a combat knife, choosing the right wet stone is essential. A wet stone, also known as a sharpening stone or whetstone, is a versatile tool that can help you achieve a razor-sharp edge on your knife.
There are a few factors to consider when selecting the right wet stone for sharpening your combat knife:
Grit size
The grit size of a wet stone determines how coarse or fine the stone is. Coarse grit stones, such as those with grit sizes ranging from 120 to 400, are best for repairing heavily damaged or dull blades. Medium grit stones, with grit sizes ranging from 700 to 2000, are ideal for regular maintenance and sharpening. Fine grit stones, typically above 3000, provide a polished finish and are great for refining and honing an already sharp edge.
It’s important to choose a wet stone with the appropriate grit size based on the condition of your combat knife and your desired level of sharpness.
Type of wet stone
There are various types of wet stones available, including natural stones like Arkansas stones and synthetic stones like aluminum oxide or diamond stones. Natural stones are known for producing a high-quality edge, but they require more maintenance and can be expensive. Synthetic stones, on the other hand, are more affordable and require less maintenance.
Consider your budget, sharpening needs, and personal preferences when deciding between natural or synthetic wet stones.
Size and shape
The size and shape of a wet stone can affect your sharpening experience. Larger stones provide a wider surface area, allowing for longer strokes and faster sharpening. However, smaller stones are more portable and easier to maneuver.
Additionally, some wet stones come in different shapes, such as rectangular, square, or round. The shape you choose depends on your comfort and the type of blade you are sharpening.
To summarize, when choosing a wet stone for sharpening your combat knife, consider the grit size, type of stone, and size and shape that best suit your needs. Taking the time to select the right wet stone will ensure that you achieve optimal results and maintain the sharpness of your combat knife.
Gathering the necessary tools
Before you can start sharpening your combat knife with a wet stone, you will need to gather a few essential tools. Having the right equipment will ensure the best possible results and make the sharpening process easier.
- A combat knife – Make sure you have a quality combat knife that needs sharpening. Check for any damage or nicks on the blade.
- A wet stone – This is the main tool you will use to sharpen your knife. A wet stone, also known as a sharpening stone or whetstone, is specifically designed for sharpening blades.
- Water – Wet stones require water to function properly. Fill a container with water and keep it nearby to wet the stone during sharpening.
- Lubricant – Some wet stones may require a lubricant to enhance the sharpening process. Check the instructions that come with your wet stone to see if lubrication is necessary.
- A flat surface – Find a stable, flat surface to place the wet stone on while sharpening. This could be a table or a workbench.
- A towel or rag – Keep a towel or rag handy to wipe the blade and stone during sharpening. This will help remove any metal particles or debris that may accumulate.
- A sharpening guide (optional) – If you are new to sharpening knives or want to ensure consistent results, you can use a sharpening guide. This tool helps maintain the correct angle while sharpening.
Make sure you have all these tools ready before you begin sharpening your combat knife with a wet stone. Having everything prepared will save you time and make the process more enjoyable.
Sharpening process
The process of sharpening a combat knife with a wet stone requires precision and attention to detail. Follow these steps to ensure a sharp and effective blade:
1. Preparation
Before you begin sharpening your combat knife, gather all the necessary tools: a wet stone, lubricating oil or water, a towel or rag, and a knife sharpening guide (optional but recommended for beginners). Choose a well-lit and clean workspace.
2. Soak the wet stone
Place the wet stone in a container filled with water or oil and let it soak for about 10-15 minutes. This will ensure that the stone is fully saturated and ready to use.
3. Establish the correct angle
Hold the knife at the correct angle against the wet stone. The angle will depend on the type of knife and its intended use. If you are unsure, consult the knife’s manufacturer or use a knife sharpening guide. The most common angle for combat knives is around 20 degrees.
4. Begin sharpening
Start by placing the knife’s blade against the wet stone at the chosen angle. Move the blade back and forth across the stone in a smooth and controlled motion. Apply consistent pressure and cover the entire length of the blade with each stroke.
Repeat this process several times, alternating sides of the blade to ensure an even sharpening. Remember to periodically add more lubricating oil or water to the stone to keep it wet and prevent the blade from overheating.
5. Test the sharpness
After sharpening, carefully wipe off any residue or debris from the blade with a towel or rag. Test the sharpness of the knife by gently running your finger along the edge. Be cautious and use light pressure to avoid injury.
If the blade still feels dull, repeat the sharpening process. If the knife feels sharp and cuts effortlessly, move on to the final step.
6. Finishing touches
To further refine the edge of the combat knife, you can use a finer grit wet stone or a leather strop. This will help remove any burrs or imperfections left from the initial sharpening process and give the blade a polished finish.
Once you are satisfied with the sharpness and finish of the combat knife, clean and dry it thoroughly before storing or using it.
