Sharp knives are essential for any kitchen, making food preparation easier, safer, and more enjoyable. However, even the best knives will eventually lose their edge with regular use. Learning how to properly sharpen your kitchen knives is a valuable skill that can save you money and ensure your knives always perform at their best. In this comprehensive guide, we'll explore various Knife Sharpening Techniques, tools, and tips to help you maintain razor-sharp blades in your kitchen.
Before diving into the specifics of sharpening, it's important to understand what happens when you sharpen a knife. Sharpening involves removing small amounts of metal from the blade to create a new, sharp edge. This process is different from honing, which realigns the edge without removing material.
There are several tools available for sharpening kitchen knives, each with its own advantages and learning curve:
Whetstones are traditional sharpening tools that offer precise control and excellent results. They come in various grits, from coarse to fine, allowing you to progressively refine the knife's edge.
Whetstone sharpening
To use a whetstone:
1. Soak the stone in water for 10-15 minutes.
2. Place the stone on a non-slip surface.
3. Hold the knife at a consistent angle (usually 15-20 degrees) against the stone.
4. Draw the blade across the stone, from heel to tip, maintaining the angle.
5. Repeat on both sides of the blade, progressively moving to finer grits.
Whetstone sharpening requires practice but offers the most control and best results for serious knife enthusiasts.
While not strictly a sharpening tool, a honing steel is essential for maintaining your knife's edge between sharpenings.
Honing steel
To use a honing steel:
1. Hold the steel vertically with the tip resting on a cutting board.
2. Place the heel of the knife against the top of the steel at a 15-20 degree angle.
3. Draw the knife down and across the steel, maintaining the angle.
4. Repeat 5-10 times on each side of the blade.
Regular honing can significantly extend the time between full sharpenings.
Electric sharpeners offer convenience and speed but may remove more metal than necessary and provide less control than manual methods.
Electric knife sharpener
To use an electric sharpener:
1. Turn on the sharpener.
2. Slowly draw the knife through each slot, from heel to tip.
3. Use light pressure and follow the manufacturer's instructions for the number of passes.
While electric sharpeners are easy to use, they may not be suitable for high-end or Japanese knives.
Manual pull-through sharpeners are a middle ground between whetstones and electric sharpeners. They're more affordable and easier to use than whetstones but offer more control than electric models.
Manual knife sharpener
To use a manual sharpener:
1. Place the sharpener on a flat surface.
2. Draw the knife through the coarse slot 3-5 times.
3. Repeat with the fine slot to polish the edge.
These sharpeners are good for maintaining moderately sharp edges but may not achieve the same level of sharpness as whetstones.
Maintaining the correct angle is crucial for effective sharpening. Most Western-style knives have a 20-degree angle per side, while many Japanese knives use a 15-degree angle. Some specialized knives may have different angles.
Blade angle guide
To find the right angle:
1. Place the knife on a cutting board with the edge facing away from you.
2. Imagine the blade divided into thirds vertically.
3. Raise the spine of the knife until the middle third is touching the board.
4. This approximates a 20-degree angle.
Practice maintaining this angle consistently throughout the sharpening process.
Regardless of the tool you choose, certain techniques apply to all sharpening methods:
1. Consistency: Maintain a consistent angle throughout the sharpening process.
2. Pressure: Use light to moderate pressure, letting the abrasive do the work.
3. Motion: Move from heel to tip in a smooth, controlled motion.
4. Alternating sides: Work on both sides of the blade equally to maintain balance.
5. Progression: Start with coarser grits and progress to finer ones for a polished edge.
Proper maintenance can reduce the frequency of sharpening:
1. Use cutting boards: Always cut on appropriate surfaces, avoiding glass or stone.
2. Hand wash: Clean knives by hand and dry immediately to prevent corrosion.
3. Store properly: Use knife blocks, magnetic strips, or blade guards to protect edges.
4. Hone regularly: Use a honing steel before each use to maintain alignment.
While learning to sharpen your knives is valuable, there are times when professional services may be beneficial:
1. High-end knives: Expensive or specialty knives may benefit from expert care.
2. Damaged blades: Chips or severe dullness might require professional attention.
3. Time constraints: If you lack the time to sharpen regularly, professionals can maintain your knives.
Professional knife sharpening
Many kitchenware stores and some farmers' markets offer professional sharpening services.
Safety should always be a priority when sharpening knives:
1. Cut-resistant gloves: Wear protective gloves to prevent accidental cuts.
2. Proper lighting: Ensure good visibility to maintain the correct angle and avoid slips.
3. Clean workspace: Keep your sharpening area clean and free of distractions.
4. First aid: Have a first aid kit nearby in case of accidents.
5. Focus: Give the task your full attention to prevent injuries.
After sharpening, it's important to test the knife's edge:
1. Paper test: A sharp knife should easily slice through a sheet of paper.
2. Tomato test: The knife should cut through a tomato's skin with minimal pressure.
3. Arm hair test: Carefully and gently try to shave a small patch of arm hair (use caution).
If the knife fails these tests, it may need further sharpening or honing.
Properly sharpening your kitchen knives is a skill that requires practice and patience. By understanding the various techniques and tools available, you can maintain your knives' edges, ensuring they perform at their best for years to come. Regular maintenance, including honing and careful use, can extend the time between sharpenings and prolong the life of your knives. Whether you choose to use a whetstone, manual sharpener, or seek professional services, keeping your knives sharp will make your time in the kitchen more efficient and enjoyable.
The frequency of sharpening depends on usage, but most home cooks should sharpen their knives every 3-6 months. However, honing should be done much more frequently, ideally before each use.
Serrated knives can be sharpened, but they require special techniques or tools. Many people prefer to have serrated knives professionally sharpened to maintain the integrity of the serrations.
Honing realigns the edge of a slightly dulled blade without removing metal, while sharpening actually removes metal to create a new edge. Honing should be done more frequently to maintain the knife's edge between sharpenings.
Whetstones offer more control and are gentler on knives, making them ideal for high-quality or expensive knives. Electric sharpeners are more convenient but may remove more metal and offer less control. The choice depends on your skill level, time, and the types of knives you own.
A sharp knife should easily slice through a piece of paper without tearing, cut through a tomato's skin with minimal pressure, and be able to shave a small patch of arm hair (carefully). If your knife fails these tests, it likely needs sharpening.
