Sharpening your knife regularly is crucial for maintaining its performance and longevity. While there are numerous methods to sharpen a knife, using a built-in sharpener offers convenience and ease of use. This article will guide you through the process of sharpening a knife with a built-in sharpener, ensuring you achieve the best results.
Understanding Built-In Sharpeners
Built-in sharpeners, often found on knife blocks or individual knife sheaths, are designed to maintain the edge of your knife. They typically consist of a pair of ceramic or diamond-coated rods that grind the blade's edge. Understanding how these sharpeners work is key to using them effectively.
Preparing Your Knife
Before sharpening, ensure your knife is clean and dry. Food particles or moisture can damage the sharpener or cause it to slip, potentially leading to accidents. If your knife has a non-stick coating, avoid using the sharpener as it can damage the coating.

Sharpening the Knife
Follow these steps to sharpen your knife using a built-in sharpener:
- Place the knife in the sharpener, ensuring the blade's edge is in contact with the rods.
- Apply steady, gentle pressure while pulling the knife through the sharpener. Do not force the blade.
- Sharpen at a consistent angle, usually around 15-20 degrees for most kitchen knives.
- Repeat the process on the other side of the blade to maintain a symmetrical edge.
- Sharpen in one direction only. Pulling the blade back and forth can cause damage to the edge.
- Sharpen in multiple passes. A few light passes are better than one heavy one.
Sharpening Different Types of Knives
While the process is similar for most knives, there are some variations:
- Serrated Knives: Use a pull-through sharpener designed for serrated knives. These sharpeners have a different mechanism that accommodates the teeth of the blade.
- Straight Razors: While built-in sharpeners can maintain the edge, they may not provide the same level of sharpness as traditional stropping or honing methods.
Maintaining Your Knife's Edge
Regular honing is key to maintaining your knife's edge between sharpening sessions. Built-in sharpeners can be used for honing, but a honing steel or rod is often more effective. Always store your knives properly to prevent damage to the blade.

When to Replace Your Built-In Sharpener
Over time, built-in sharpeners can become dull or damaged. If you notice a decrease in performance or visible damage to the rods, it's time to replace the sharpener. This is typically every 1-2 years, depending on usage.
Sharpening your knife with a built-in sharpener is a convenient way to maintain a sharp edge. By understanding the process and using the sharpener correctly, you can extend the life of your knife and ensure it performs at its best. Happy cooking!
