Sharp knives are essential tools in any kitchen, whether you're a professional chef or a home cook. Properly sharpened knives not only make food preparation easier and more efficient but also safer, as dull blades are more likely to slip and cause accidents. In this comprehensive guide, we'll explore various professional knife sharpening techniques, tools, and maintenance tips to keep your kitchen knives in top condition.
Before diving into specific sharpening techniques, it's crucial to understand the basics of knife sharpening. Sharpening a knife involves removing small amounts of metal from the blade to create a new, sharp edge. This process differs from honing, which realigns the existing edge without removing significant amounts of metal.
One of the most critical aspects of knife sharpening is maintaining the correct angle between the blade and the sharpening surface. Most Western-style kitchen knives have a 20-degree angle on each side of the blade, while many Japanese knives have a 15-degree angle. Maintaining this angle consistently throughout the sharpening process is key to achieving a sharp, durable edge.
Whetstone sharpening is considered one of the most effective and precise methods for sharpening kitchen knives. This technique involves using a rectangular stone with different grits on each side.
Steps for whetstone sharpening:
1. Soak the whetstone in water for about 10-15 minutes.
2. Place the stone on a non-slip surface with the coarser grit facing up.
3. Hold the knife at the correct angle (usually 15-20 degrees) against the stone.
4. Draw the blade across the stone, from heel to tip, maintaining the angle.
5. Repeat this motion 10-15 times on each side of the blade.
6. Flip the stone to the finer grit side and repeat the process.
7. Finish by honing the blade with a honing steel.
Electric knife sharpeners offer a quick and convenient way to sharpen kitchen knives, especially for those who may not have the time or skill to use a whetstone.
Steps for using an electric knife sharpener:
1. Turn on the sharpener and identify the coarse and fine slots.
2. Start with the coarse slot for very dull knives, or the fine slot for routine maintenance.
3. Hold the knife handle firmly and draw the blade through the slot from heel to tip.
4. Apply light pressure and pull the knife through at a steady pace.
5. Repeat 3-5 times on each side of the blade.
6. If using the coarse slot, finish with a few passes through the fine slot.
Whetstones come in various grits, typically ranging from 220 (very coarse) to 8000 (extremely fine). For most kitchen knives, a combination stone with 1000/6000 grit is suitable for both sharpening and refining the edge.
A honing steel is essential for maintaining the edge between full sharpenings. It realigns the microscopic teeth of the blade, extending the time between sharpenings.
These devices offer convenience and consistency, with preset angles and multiple stages for sharpening and honing.
While not as precise as other methods, these compact sharpeners are useful for quick touch-ups and are very user-friendly.
Proper maintenance can significantly extend the time between sharpenings and prolong the life of your knives.
1. Always hand wash and dry your knives immediately after use.
2. Store knives in a knife block or on a magnetic strip to protect the edges.
3. Use appropriate cutting boards (wood or plastic) to prevent dulling.
4. Avoid cutting on hard surfaces like glass, marble, or ceramic.
Use a honing steel regularly (ideally before each use) to maintain the knife's edge. This quick process realigns the edge without removing metal, keeping the knife sharp between full sharpenings.
Chef knives, being the workhorses of the kitchen, require special attention when it comes to sharpening.
1. Coarse Sharpening: Use a coarse whetstone or the coarse stage of an electric sharpener to reset the edge on very dull knives.
2. Fine Sharpening: Refine the edge using a finer grit stone or the fine stage of an electric sharpener.
3. Polishing: Use a very fine grit stone or a leather strop to polish the edge for maximum sharpness.
For those looking to take their knife sharpening skills to the next level, consider these advanced techniques:
Over time, repeated sharpening can thicken the edge of the knife. Thinning involves grinding the sides of the blade to maintain its original geometry.
A microbevel is a small, secondary bevel at a slightly steeper angle than the primary bevel. This can increase edge durability without sacrificing sharpness.
Mastering the art of professional knife sharpening takes time and practice, but the results are well worth the effort. Sharp knives not only make cooking more enjoyable but also safer and more efficient. By understanding the various sharpening techniques and tools available, and by implementing proper maintenance habits, you can keep your kitchen knives in top condition for years to come.
The frequency of sharpening depends on how often you use your knives and how well you maintain them. For home cooks, sharpening every 3-6 months is typically sufficient, with regular honing in between. Professional chefs may need to sharpen their knives weekly or even daily.
Serrated knives require special sharpening techniques. While the flat side can be sharpened like a regular knife, the serrated side needs a specialized sharpening rod or a professional service.
For most home cooks, learning to sharpen knives at home is a valuable skill. However, if you have expensive or specialty knives, or if you're not confident in your sharpening abilities, a professional service can ensure your knives are sharpened correctly without risk of damage.
Honing realigns the edge of the blade without removing metal, while sharpening actually grinds away metal to create a new edge. Honing should be done regularly (even daily), while sharpening is needed less frequently.
Yes, whetstones can be used to sharpen a variety of tools, including pocket knives, scissors, chisels, and even some garden tools. However, the technique may vary depending on the tool and its intended use.
