What is the best grind for a kitchen knife?

You want a kitchen knife that slices smoothly and stays sharp with little effort. Most experts recommend a flat or convex grind for this reason. These grinds help you keep a thin edge, so you get great cutting performance, even if you are just starting out. The flat grind works especially well for slicing vegetables like tomatoes, while the convex grind reduces drag and keeps the edge strong. To get the best results, you need the right tool—a reliable knife grinder makes all the difference.

Key Takeaways

• Choose a flat or convex grind for kitchen knives. These grinds offer sharpness and durability, making slicing easier.

• Flat grinds excel at slicing vegetables and general kitchen tasks. They provide a balance of strength and sharpness.

• Convex grinds are strong and maintain sharpness longer. They are ideal for heavy use and tough materials.

• Invest in a reliable 2x72 belt grinder for knife making. This tool offers durability and precision for shaping your knives.

• Always prioritize safety when using a knife grinder. Wear protective gear and keep your workspace organized.

Best Grind Types

When you start exploring knife making, you’ll notice that the grind of your kitchen knife changes everything about how it feels and performs. Let’s break down the three most common kitchen knife grinds so you can pick the one that fits your cooking style.

Flat Grind

The flat grind stands out as a favorite in knife making, especially for kitchen knives. You’ll see this grind on many chef’s knives because it offers a great balance between strength and sharpness. The grind runs in a straight line from the spine of the blade down to the edge, creating a thin, sharp cutting surface.

Here’s a quick look at what makes the flat grind special:

You’ll love how a flat grind slices through tomatoes, apples, and other veggies. The blade glides through food with almost no resistance. That’s why so many people choose this grind for knife making projects at home. Flat grinds are stronger than hollow grinds and cut better than sabre grinds. You get a blade that’s thin enough for precision but still tough enough for daily use.

Tip: If you’re just starting out in knife making, try a flat grind first. It’s easier to sharpen and maintain, especially if you use a belt grinder knife sharpener.

Flat grind knives shine when you need smooth, even cuts. You’ll find them perfect for slicing vegetables, meats, and just about anything else you prep in the kitchen.

Convex Grind

The convex grind is another popular choice in knife making. This grind curves outward from the spine to the edge, giving you a blade that’s both strong and sharp. Many knife makers love the convex grind because it holds up well under heavy use.

Check out these advantages:

You’ll notice that convex edges tend to last longer. Many of the sharpest knives in knife making have convex edges. The rounded shape means less drag as you cut, so you can slice through meat or tough veggies with less effort. If you want a kitchen knife that stays sharp and resists chipping, the convex grind is a smart pick.

Note: Convex grinds can be a bit trickier to sharpen by hand. Using a knife sharpener belt grinder makes the process much easier and helps you keep that perfect edge.

Hollow Grind

The hollow grind has a unique look and feel. Knife making enthusiasts often use this grind for specialty kitchen tools. The blade curves inward, creating a very thin edge. This design makes hollow grind knives incredibly sharp, but also more delicate.

You’ll see hollow grind knives used for:

• Fillet knives, where you need a super fine edge for delicate cuts.

• Specialty kitchen tasks that require precision and minimal resistance.

However, there are some drawbacks to consider:

• Hollow grinds can deflect more than flat or convex grinds, which means the blade might wobble during cutting.

• They tend to wedge when you cut through firm or rigid foods, making them less effective for everyday kitchen use.

• The thin cross-section increases the risk of blade failure if you use the knife for chopping or heavy-duty tasks.

If you’re into knife making and want to experiment, try a hollow grind for a fillet knife or a tool that needs a razor-sharp edge. For most kitchen knives, though, you’ll probably prefer the flat or convex grind for their strength and versatility.

Remember: Hollow grinds are best for light, precise work. If you want a reliable all-purpose kitchen knife, stick with flat or convex grinds in your knife making projects.

How to Grind

Preparation Steps

Before you start grinding, you need to set yourself up for success in knife making. Start by cleaning your blade to remove any dirt or food residue. This helps you get a smooth finish and keeps your tools in top shape. Next, gather your essentials for knife making:

• Honing steel

• Sharpening steel

• Electric knife sharpener or grinding machine

• Pull-through sharpener

• Knife sharpener with an integrated sharpening stone

Professional knife making always begins with careful marking. Use a drill bit with a fine point to mark the centerline of your blade. Paint the blade with a sharpie each time you change the angle. Leave a little extra thickness if you plan to create a double bevel. Place a small block of wood under the end of your knife to keep it steady. Work in broad strokes to avoid low spots that are tough to fix later.

Tip: Good preparation in knife making saves you time and helps you avoid mistakes down the line.

Grinding Process

Now you’re ready to shape your blade. In knife making, always start with a clean piece of steel or a rough-forged blade. Trace your knife silhouette with a sharpie. If you use an angle grinder, clamp your steel and rough out the shape before moving to your belt grinder knife sharpener.

Secure your grinder to the workbench. Use both hands to guide the blade, keeping your elbows close for control. Switch hands when grinding both sides—this builds skill and keeps your knife making even. Always keep a bucket of water nearby to cool your blade and prevent overheating.

Begin with a coarse grit belt (P36 to P150) for shaping and beveling. Draw guide lines on your blade and grind smoothly from edge to spine. Adjust belt tracking to get the plunge line you want. Move to a finer grit (P180 to P220) for sharpening. For the best results in knife making, finish with hand sanding.

Don’t rush. Light pressure prevents heat build-up and keeps your blade from warping.

Finishing Touches

Finishing is where your knife making skills shine. Use two or three wet sharpening stones to refine the edge until it shaves hair. Hone the blade on a leather strop with chromium oxide for a razor-sharp finish. For a super fine edge, try a prototype water stone.

Polish your blade by moving from a coarse to a fine stone. Strop on a plain sheet of paper over an oiled stone to remove burrs. Some knife making pros even use a champagne cork or balsa wood for final stropping. Adjust the edge thickness for your knife’s purpose—a slicing knife needs a thinner edge than a chopping knife.

A polished, burr-free edge is the mark of great knife making. Take your time and enjoy the process.

Common Mistakes

Grinding kitchen knives with a Knife Grinder can feel rewarding, but you might run into some common mistakes. If you know what to watch for, you’ll get better results with your belt grinder knife sharpener and keep your knife grinds in top shape.

Overheating

You might notice your blade getting hot while using a knife sharpener belt grinder. That’s a warning sign. If you grind only at the sharp edge, friction heats up the steel quickly. The thin edge expands more than the rest of the blade, which can cause microfractures. Harder steel makes this problem worse because it’s more brittle.

When grinding an edged tool, be it a knife or a chisel, if you are grinding only at a sharp edge, the friction will heat the edge much more than the steel further back in the bevel. This results in the thin edge expanding more than the base metal, and can easily result in microfractures along the edge. The harder the material, the worse the problem as it is inevitably more brittle than softer material.

To avoid overheating, dip your blade in water often and use light pressure. If you see any discoloration, stop and let your knife cool down.

Angle Errors

Getting the right angle with your Knife Grinder matters. If you mix up inclusive and exclusive angles, you might sharpen your knife incorrectly. You need to match the angle to your knife’s purpose. For example, a chef’s knife needs a different angle than a fillet knife. Steady pressure helps you keep the edge consistent.

• Using the wrong type of angle can lead to poor sharpening. Always check your measurement system.

• Varying pressure during sharpening affects the edge. Keep your pressure steady.

• Choosing the wrong angle for your knife can hurt performance. Research your knife type before grinding.

If you use a belt grinder knife sharpener, set your angle carefully and check it often. This helps you get the best knife grinds for your kitchen tasks.

Skipping Maintenance

Skipping maintenance is a mistake you want to avoid. Dull knives need more force and can cause injuries. Always inspect your knives for damage before you use them. Store them safely to prevent accidents.

• Keep your knives sharp for safety and performance.

• Inspect for damage before each use.

• Store knives properly to avoid accidents.

• Sharpen regularly and use the right technique and angle.

Neglecting your knife grinds and forgetting to clean your blade before sharpening can lead to poor results. Always finish with a final polish to get a smooth edge. Your Knife Grinder and knife sharpener belt grinder work best when you maintain your tools and blades.

Choosing a flat or convex grind gives you a kitchen knife that stays sharp and cuts smoothly. You get long-term benefits like easy slicing and less maintenance. Here’s a quick look:
