Sharpening a knife with a wet rock is an easy, effective way to hone your blade. You should, however, take some safety precautions before beginning the sharpening process. Make sure you have a high-quality wet rock that won’t break when coming into contact with your knife. Additionally, secure a non-slip surface in front of where you plan to be working so that your work area remains stationary and safe. Avoid anything rough like concrete which may discolor or damage your blade; instead, use a wooden cutting block or other flat, sturdy surface. Keep in mind that all of the steel chips generated during the sharpening process will need to be collected properly and disposed of accordingly.

Once you have set up a safe workspace, begin by wetting the rock and applying 20-40 strokes to each side of the blade at roughly 10 degrees from horizontal. If you happen to over sharpen one of the sides, simply reduce the angle by five degrees for more consistent honing between both surfaces. After each pass with the stone, feel free to use a honing oil or water for lubrication and cooling purposes. This will prevent burrs from forming along the edge and ensure that each stroke is evenly distributed. Ultimately it’s up to you how many times you will want to repeat this cycle; if you’re satisfied with what you can already see then feel free stop after two passes per side and give it another test run before completely reassembling the knife handle and sheath – now your knife is ready for anything!

Materials and Tools Needed

1. Before starting, you will need a selection of wet rocks with differing grits. A coarse grit of around #200 is ideal for sharpening a dull blade, while a finer grit of around #1000 is better suited to maintaining the sharpness of already-sharp blades.

2. You will also need a water supply and a stone holder or other stabilizing object to keep the rock at an ergonomic angle as you sharpen the knife with it.

3. Place your chosen wet rock into the stone holder and pour clean water onto the rock until it’s thoroughly moistened. This helps to lubricate and refine the edge of your blade while you’re sharpening it.

4. With just enough pressure, slowly drag your knife against the wet rock in a sweeping motion from one side to another, using either a circular sawing motion or outward strokes toward the tip of the knife – whichever works best for you. Remember to make sure that both sides of the knife are evenly polished along its entire length in order to keep its balance. Make sure not to push too hard – use only enough pressure for your blades cutting edge to meet the surface of this wet rock without forcing it too deeply into it.

5. When done, wipe off any excess moisture from the blade and proceed on to another type of wet rock with finer grit if necessary – again, making sure that both sides are evenly polished along its entire length in order to maintain balance between them (if needed). If desired, you can finish off by honing your blade with an appropriate honing steel after sharpening it with this wet stone method for a razor-sharp edge!

Identifying the Grit of the Wet Rock

When sharpening your knife with a wet rock, you should start by determining the grit of the rock. The grit number helps you identify how coarse or fine the stone is and indicates what type of edge it can produce. This will help you decide if it is suitable for your needs. To determine the grit of your wet rock, examine it closely, then compare its texture against pictures in a standard grit chart. If the wet rock appears to be much smoother than any in the chart, try rubbing it against paper or glass. The scratches the stone leaves behind on those surfaces will provide more information that can be used to match your stone against ones from a reference chart. Depending on what type of edge you want, whether a quick-and-sharp finish or something finer and longer lasting, you may use any number of stones. Coarse stones are for restoring an extremely dull blade while fine stones are used for creating a smooth edge.

Safety Tips

When sharpening a knife with a wet rock it’s critical to wear the appropriate safety wear. This includes wearing goggles, long sleeves and closed-toe shoes to protect your eyes and skin from splinters of stone or an accidental slip of the knife blade. An apron can also be helpful in protecting clothing from sharpening particles or any other messes created during the process. Similarly, using rubber gloves is recommended when handling the wet rock itself, as some types of rock can contain harmful contaminants such as silica which can easily be inhaled without protection. Another important precautionary measure is working on a non-slippery surface, as smooth surfaces are more prone to slips and falls while you’re concentrating on getting your edge just right. Also, if you’re not familiar with sharpening knives with a wet rock it’s highly recommended that you seek guidance from an expert or watch tutorial videos first.

Step-by-Step Guide

1. Wet the stone: Fill a bowl up with water and soak the wet stone in it for 30 minutes before using it. This will help to soften the stone and prevent damage to the blade.

2. Place the stone on a stable surface: Place the wet stone on a damp cloth, cutting board or other stable surface. Avoid putting it directly onto hard surfaces, as this could damage your knife’s edge.

3. Angle the blade: Lay the knife flat on top of the wet stone at an angle of around 20 degrees away from you, making sure both sides of your blade are placed evenly along each side of the stone. This angle is considered optimal for most knives when sharpening them with a wet-stone method.

4. Sharpen one side of your blade: Place one side of your knife against the wet stone making sure to maintain its angle and slowly move it from one end of the stone to another in long, smooth strokes, pushing down gently as you do so. Make sure to sharpen both sides of your knife equally before moving onto polishing them with a finer grit finish below!

5. Remove burrs and refine edge with finishing touches: Take some time now to remove any burrs that may have formed during sharpening or refine your blades’ edges once sharpening has been completed by using finer abrasive stones if needed until you have achieved a polished finish along both sides and all your blades’ edges!

Common Mistakes

Sharpening a knife with a wet rock requires patience and dedication. Before beginning, one should orient their body in such a way that they are able to safely execute the task; this means that they should position themselves in front of the rock or stone with proper stance. To begin, you will need to lubricate the sharpening surface of the rock by adding some water so that it becomes slightly slippery and reduce resistance while sharpening. Once you have the right amount of moisture, start sharpening the blade of your knife by making sure it’s slightly on the angle, then draw the blade across the surface while moving in a fluid motion. Be sure to roll, rather than press down too hard on your knife; this could cause damage or an uneven edge. Make sure to run both sides of your blade across the surface before test it out by cutting through paper to see if it’s sharpened effectively. When it comes time to stop sharpen your knife, try not to overdo it as each press will strip away at steel and make blades dull more quickly. Knowing when to stop is also important as pressing too much can cause ridges on your blade which can be irritating while cutting or affect its final appearance.


Sharpening blades regularly with a wet rock is an easy and inexpensive way to maintain the life of your knives. After sharpening, be sure to clean and store your knife properly. An oiled cloth is recommended for wiping down the blade before storage. Additionally, keep your rock in its own designated container so it does not become damaged or wet when not in use. Finally, carefully check the sharpness of your knives every few weeks to ensure they are properly maintained. With regular care and maintenance, your knives will stay razor-sharp for many years to come!
