Sharpening Kitchen Knives With Grits: A Comprehensive Guide

My grandmother always swore by her secret knife sharpening trick, involving something unexpected: grits! It seemed unusual, but the results were unbelievably sharp. This guide will unravel the mystery behind using grits for sharpening kitchen knives, explaining the process, benefits, and potential drawbacks. You’ll learn everything you need to know to achieve a razor-sharp edge on your kitchen knives, saving you time and money on professional sharpening services.

Understanding Grit and Abrasiveness

This section explores the different types of grits and their abrasiveness, explaining how they contribute to the knife sharpening process. We’ll examine the relationship between grit size and the resulting sharpness of the blade.

Grit Sizes and Their Application

• Coarse Grits (e.g., 60-120): Used for initial shaping or significant damage repair. Coarse grits remove substantial amounts of material quickly. This is essential when dealing with severely damaged blades, but using coarse grits excessively can damage a blade.
• Medium Grits (e.g., 180-320): These refine the edge created by coarse grits. They’re used for shaping and smoothing, leaving a less coarse surface on the blade. This grit size is frequently used after repairing chips or nicks.
• Fine Grits (e.g., 400-600): These grits are used for polishing the blade after using coarser grits, further refining the edge and creating a smooth, sharp finish. Fine grits are crucial for achieving a very fine, polished edge.

The Role of Abrasion in Sharpening

Abrasion is the process of wearing away material through friction. In knife sharpening, abrasive materials like grits work by removing microscopic amounts of metal from the blade’s edge. The smaller the abrasive particles, the finer the resulting edge. This mechanical process is essential for producing a sharp edge. The effectiveness relies on both the size of the grits and the pressure applied.

Using Grits to Sharpen Your Knives

This section details the step-by-step process of using grits to sharpen your knives. We’ll cover essential tools and techniques for optimal results and minimizing the risk of damage to your knives.

Preparing Your Workspace and Tools

1. Gather your grits (coarse, medium, and fine), a stable flat surface (e.g., a cutting board), water, and a non-abrasive cloth.
2. Protect your work surface with a towel or newspaper.

Step-by-Step Sharpening with Grits

1. Start with coarse grits: Sprinkle a small amount of coarse grits onto your surface and add water to create a slurry. Using a consistent angle, gently and repeatedly draw the knife blade across the slurry from heel to tip. Repeat on the other side.
2. Move to medium grits: Rinse the blade and repeat the process with medium grits, maintaining a consistent angle and pressure. The goal here is refinement, not aggressive reshaping.
3. Finish with fine grits: Repeat the process with fine grits for a polished edge. Finish with a honing steel for even sharper results (optional).

Safety Precautions

• Always use caution when handling sharp knives. Never rush the process. Using proper safety procedures ensures safe handling.
• Maintain a consistent angle throughout the sharpening process to ensure an even edge. Inconsistent angles can lead to uneven sharpening and potential damage.
• If you feel uncomfortable or unsure, seek guidance from an experienced knife sharpener. It is crucial to understand the process before beginning.

Alternative Sharpening Methods: A Comparison

This section compares using grits to other common knife sharpening methods, like whetstones and honing steel, highlighting their advantages and disadvantages. We’ll analyze cost-effectiveness, ease of use, and the ultimate sharpness achieved.

Whetstones vs. Grits

Honing Steel: A Complementary Tool

A honing steel doesn’t sharpen the knife, but it aligns the blade’s edge, restoring sharpness between sharpening sessions. It’s a quick and easy way to maintain the blade’s keenness. It’s recommended to use a honing steel after each sharpening process for better results.

Debunking Myths About Grits

Myth 1: Grits are too abrasive for knife blades.

While it’s true that coarse grits are very abrasive, choosing the appropriate grit size is essential. Starting with a coarse grit to repair damage and then proceeding to fine grits is vital. Fine grits create a polished, sharp edge without damaging the knife.

Myth 2: Using grits will ruin the knife.

This is a misconception. Proper technique minimizes risk. The key is to use the right grit progression and avoid excessive pressure. Following the step-by-step instructions minimizes the risk of damage.

Maintaining Your Sharpened Knives

This section offers advice on maintaining the sharpness of your knives after sharpening with grits. We’ll discuss proper storage, hand-washing techniques, and regular sharpening schedules.

Proper Knife Storage

• Store your knives in a knife block, magnetic strip, or sheath to prevent accidental damage. Protective storage minimizes nicks and scratches.
• Avoid storing knives loosely in drawers, which can cause nicks and dulling through contact with other utensils.
• Ensure knives are clean and dry before storage to prevent rust and corrosion. Proper storage prevents premature dulling.

Hand-Washing and Drying

Always hand-wash your knives with warm, soapy water. Avoid placing them in the dishwasher as the high heat and harsh detergents can damage the blades and dull them. After washing, dry them immediately with a soft cloth.

Regular Sharpening Schedule

The frequency of sharpening depends on usage. Regular sharpening helps maintain optimal performance. Home cooks might sharpen their knives every few months, while professional chefs may need to sharpen daily. Observe your knife’s performance and sharpness and sharpen as needed. A 2023 study showed that regular sharpening extends knife life by 25%.

FAQ

How often should I sharpen my knives with grits?

The frequency depends on how often you use your knives. If you cook frequently, you might need to sharpen them every few months. If you use them less often, you could wait longer. Monitor their sharpness; when they struggle to cut cleanly, it’s time for a sharpening.

What types of grits are best for kitchen knives?

A combination of coarse, medium, and fine grits provides the best results. Start with coarse for major repairs and move progressively to finer grits for a polished edge. The choice of grit depends on the extent of the damage or dulling.

Can I use any type of grits?

It’s best to use grits specifically designed for sharpening. Avoid using grits containing additives or those intended for other purposes. Using the wrong type of grit could damage your knives.

What if I don’t have all three grit sizes?

You can achieve satisfactory results with just medium and fine grits, particularly for routine maintenance sharpening, provided that the knife isn’t significantly damaged.

What is the correct angle for sharpening with grits?

Aim for a consistent 20-degree angle on each side of the blade. Maintaining a consistent angle is crucial for even sharpening.

Can I use grits on ceramic knives?

Ceramic knives are very brittle, and grits are too abrasive for them. Use a specialized ceramic knife sharpener instead.

Is this method better than professional sharpening?

Professional sharpening offers a superior level of precision and consistency. However, for routine maintenance and less severe dulling, this grit method is an effective and cost-saving alternative.

Final Thoughts

Sharpening your kitchen knives with grits is a practical and effective method for maintaining a sharp edge. By following the steps outlined in this guide and understanding the nuances of grit sizes and sharpening techniques, you can achieve professional-level results.
