The short answer: To keep your knife set sharp, hand wash with mild soap and warm water, dry immediately, use a honing rod regularly, sharpen with whetstone or electric sharpener when needed, and store in a block or on a magnetic strip. Avoid dishwasher and cutting on hard surfaces.

Your knives might be labeled dishwasher safe, but the truth is, dishwashers are knife killers. The high heat, harsh detergents, and rattling against other utensils can dull the edge and warp the blade. Food particles and acids from leftovers can also cause corrosion and staining. For a knife set that stays sharp, hand washing is the way to go.
When you hand wash, use a soft sponge or cloth with mild dish soap and warm (not hot) water. Avoid abrasive scrubbers as they can scratch the blade. Clean each knife individually, paying attention to the handle and the bolster (if present). After washing, rinse thoroughly and dry immediately with a soft towel. Never let your knives air dry because water spots and potential rust can develop, especially on high carbon stainless steel.
Drying might seem straightforward, but it’s a step many skip. Always dry your knives right after washing. This prevents water spots and reduces the risk of rust. Use a clean, soft microfiber cloth or a kitchen towel. Pay special attention to the handle and the area where the blade meets the handle, as moisture can get trapped there.
For storage, avoid tossing knives loosely in a drawer. This not only dulls the edges but also poses a safety risk. Instead, use a wooden knife block, a magnetic strip, or blade guards. If you use a knife block, ensure the slots are clean and dry to prevent bacteria. A magnetic strip is a great space saver and keeps blades from touching other utensils. For those who travel or have limited space, blade guards are an excellent option that protects both the blade and your fingers.
Many people confuse honing with sharpening, but they are different. Honing realigns the microscopic teeth on the blade’s edge, keeping it straight and effective. Sharpening actually removes metal to create a new edge. Honing should be done regularly, ideally before each use if you’re a professional, but at least once a week for home cooks. Sharpening is needed less often, depending on how much you use your knives.
To hone, use a honing rod (also called a sharpening steel). Hold the rod vertically with the tip on a stable surface. Place the heel of the blade against the rod at a 15-20 degree angle, then draw the blade down and across the rod, sweeping from heel to tip. Repeat on the other side. Do this 5-10 times per side. This simple routine keeps your knives performing at their best.
When honing isn’t enough, you need to sharpen. There are three common methods: whetstone, electric sharpener, and pull-through sharpener. Whetstones offer the most control and give the finest edge, but they require practice and time. You’ll need to soak the stone in water, then hold the knife at a consistent angle (usually 15-20 degrees) and slide it across the stone in a sweeping motion, using different grits to achieve a polished edge.
Electric sharpeners are quick and easy, but they remove more metal than necessary if used too often. They often have guided slots that set the angle for you. Pull-through sharpeners are affordable and simple to use, but they can create a burr if not used correctly. For most home cooks, a good pull-through or electric sharpener is sufficient. If you’re considering a new knife set, you might want to invest in one that includes a sharpener or a set that is easy to maintain. You can find top rated options in our best knife sets guide.
Your cutting board is a silent factor in blade dullness. Hard surfaces like glass, stone, or ceramic can quickly dull your knives. Even some plastic boards are too hard. The best materials are wood (like maple, walnut, or cherry) and bamboo, which are gentle on edges. End-grain wood is considered the best because the knife cuts between the wood fibers, keeping the edge sharp longer.
Avoid cutting on countertops, plates, or metal surfaces. If you only have a glass board, consider replacing it with a wood or high quality plastic board. Also, clean your cutting board regularly to prevent bacteria, but avoid soaking it. Oil wooden boards with mineral oil periodically to keep them from drying and cracking.
Even with the best intentions, many people unknowingly damage their knives. Using a dishwasher is a top mistake, as mentioned. Also, using the wrong cutting surface, such as glass or granite, is a common error. Another mistake is putting knives in a drawer without any edge protection, which causes them to knock against other utensils. Cutting through bones or frozen foods can chip the blade, so use a cleaver for such tasks. Finally, letting knives sit in the sink or soaking them can lead to rust and dullness. Always clean and dry promptly.
You should also avoid using your knives for tasks they weren’t designed for, like opening cans or prying lids. This can bend the tip or break the blade. Always use the right knife for the job. For example, use a chef’s knife for chopping, a serrated knife for bread, and a paring knife for small intricate work.
It depends on usage. For a home cook who uses knives a few times a week, sharpening every 3-6 months is a good rule of thumb. If you notice that your knife isn’t cutting as well even after honing, it’s time to sharpen. For heavy daily use, you might need to sharpen monthly.
It’s not recommended. Glass is extremely hard and will dull your knives faster than any other material. Even with careful use, the micro-abrasions will wear down the blade. Switch to wood or plastic to preserve sharpness.
Yes, if you want convenience. Many knife blocks come with a slot for sharpening, which is great for quick maintenance. However, the quality of built-in sharpeners varies. They are usually pull-through types that are easy to use but may not give the finest edge. For a professional finish, consider a separate whetstone.
