What Are The Types Of Pizza Cutters?

Pizza cutters are kitchen utensils designed specifically for slicing pizza. They typically feature a circular blade attached to a handle, allowing for easy and precise cuts across a pizza’s surface.

There are primarily four types of pizza cutters you can choose from, each with their unique advantages:

1. Pizza Cutter Wheel: This pizza cutter is the most widely used variety. It consists of a circular blade connected to a handle, enabling you to roll the wheel over the pizza for cutting. Great for creating even slices and requires little strength to operate.

2. Rocker Pizza Cutter: This type of pizza cutter is a large, curved blade with a handle on each end. You rock it back and forth to cut the pizza. It’s ideal for cutting large pizzas quickly and is less likely to push toppings around than a wheel cutter.

3. Large Chef’s Knife: Though not a traditional pizza cutter, a large chef’s knife can do the job too. The advantage of using a chef’s knife is that it gives you better control over the size of the slices. It’s also versatile and can be used for other kitchen tasks.

4. Kitchen Shear Scissors: Some people prefer using kitchen shears for cutting pizza, especially for small or thin-crust pizzas. They give you precise control, perfect for those who want their slices cut to specific sizes.

Why Does a Pizza Cutter Become Dull?

Just like any other kitchen utensil with a blade, a pizza cutter can become dull over time due to several factors, including:

1. Low-Quality Materials

Low-quality materials can significantly contribute to the dulling of a pizza cutter.

If the blade is made from inferior metal or is poorly constructed, it can become blunt quickly. Low-quality metals are not as durable or sharp as higher-quality ones, leading them to wear down faster when cutting through the crust of a pizza.

2. Incorrect Use

Incorrect use of a pizza cutter can also lead to its blade becoming dull. There are several ways in which you might be using your pizza cutter incorrectly, causing it to lose its edge faster.

– Applying too much pressure when cutting can damage the blade

– Cutting on hard surfaces can dull the blade quickly

– Using the pizza cutter for tasks it’s not intended for, such as cutting through thick or frozen foods, can cause damage.

3. Incorrect Storage

Improper storage of a pizza cutter is another factor that can dull its blade over time. Here are some common storage mistakes that can dull a pizza cutter blade:

– Storing the pizza cutter in a drawer with other utensils can cause it to rub against hard objects, which can dull the blade over time.

– Not cleaning and drying the cutter thoroughly before storage may lead to rust, which dulls the blade.

– Leaving the pizza cutter in a damp or humid environment can cause rusting and dulling.

– Storing the cutter with the blade exposed can lead to accidental damage, dulling the blade.

How To Sharpen a Pizza Cutter Using Tools?

Now that we’ve understood why and how a pizza cutter becomes dull, let’s dive into the actual process of how to sharpen a pizza cutter using various tools.

1. Whetstone

A whetstone is a cost-effective and reliable tool for sharpening your pizza cutter. It comes in varying grit sizes – the lower the grit number, the coarser the stone, and vice versa. For a pizza cutter, a medium grit (around 1000) should suffice.

Follow these steps to sharpen your pizza cutter with a whetstone:

– Step 1: Preparation: Start by soaking your whetstone in water for about 15-20 minutes until bubbles stop forming.

– Step 2: Sharpening: Hold the cutter at a 20-degree angle against the surface of the whetstone. Apply consistent pressure and move the cutter in a circular motion around the stone. This should be done for around 5-10 strokes or until the blade feels sharp to the touch.

– Step 3: Rinse and Dry: Rinse the cutter under running water to remove any debris, and dry it thoroughly to prevent rust.

Remember, safety is paramount. Always keep your fingers away from the path of the blade when sharpening.

2. Puck Sharpener

A puck sharpener, also known as a handheld sharpener, is another efficient and easy-to-use tool to hone your pizza cutter blade. It usually has two sides – a coarse one for sharpening and a finer one for honing the edge.

Here’s how to use it:

– Step 1: Preparation: Hold the puck sharpener firmly in one hand and the pizza cutter in the other.

– Step 2: Sharpening: Start with the coarse side of the puck. Position the pizza cutter blade to maintain its original sharpening angle, which is often around 20 degrees. Using moderate pressure, move the cutter in a circular motion on the puck’s surface. Repeat this motion for about 5-10 strokes or until the blade is sharp.

– Step 3: Honing: Flip the puck over to its finer side. Maintain the same angle and repeat the back-and-forth motion for 3-5 strokes.

– Step 4: Rinse and Dry: Rinse the cutter under running water to remove any grit or metal shards, then dry it thoroughly to prevent rust.

Remember, never rush the sharpening process. Take your time to ensure you’ve evenly sharpened the blade and avoid any potential injuries.

3. Manual Knife Sharpener

A manual knife sharpener is a compact and convenient tool that can be used to keep your pizza cutter blade in top shape. Often equipped with two slots (coarse and fine), it allows you to both sharpen and hone the blade.

Here’s how you can use it:

– Step 1: Preparation: Insert the pizza cutter blade into the ‘coarse’ or ‘sharpen’ slot. Position the cutter at an angle more suited to its blade, typically around 20 degrees, rather than 90 degrees for best results.

– Step 2: Sharpening: Using moderate pressure, pull the pizza cutter through the slot several times, typically around 5-10 strokes. This process grinds away the old, dull edge and creates a new sharp edge.

– Step 3: Honing: After you’ve sharpened the blade, it’s time to refine the edge. Insert the blade into the ‘fine’ or ‘hone’ slot and repeat the process. This step removes any irregularities and polishes the blade, enhancing its cutting performance.

– Step 4: Rinse and Dry: As always, rinse the cutter under running water to remove any metal particles. Dry it thoroughly to prevent rust.

Remember, the key to effective sharpening with a manual knife sharpener is consistency. Ensure each stroke is made with even pressure and speed for a sharp, durable edge.

4. Belt Grinder

A belt grinder is a powerful tool used for heavy-duty sharpening, and it can certainly be used to sharpen a pizza cutter. Please note that this process must be done with care due to the speed and power of the belt grinder.

Here is the step-by-step process:

– Step 1: Preparation: Securely mount your belt grinder on a flat surface. Make sure the grinder’s power cord is safely out of the way. Ensure you’re wearing appropriate safety gear such as gloves and safety glasses.

– Step 2: Sharpening: Turn on the grinder. Hold the pizza cutter at a 20-degree angle to the belt, applying light pressure and moving the blade against the belt’s direction. A few passes are usually enough. Monitor the blade to prevent overheating, which can weaken it.

– Step 3: Honing: To achieve a smoother finish, you might want to hone the blade using a finer grit belt. Repeat the same process as in the sharpening step, but use light, even strokes.

– Step 4: Rinse and Dry: Lastly, rinse the cutter under running water to remove any metal particles, and then dry it thoroughly to prevent rust.

Remember, the key to sharpening with a belt grinder is moderation. Over-grinding can lead to a thin blade with a short life span.

Some Safety Tips For Sharpening Pizza Cutters

When learning about sharpening a pizza cutter, it’s paramount to keep safety in mind as sharpening tools can be dangerous if not handled properly. Here are a few safety tips to ensure your experience with sharpening your pizza cutter is safe and effective:

1. Wear Protective Gear: Always wear safety glasses to protect your eyes from sparks or metal shards that could potentially fly during the sharpening process. If you’re using a belt grinder, wearing protective gloves and a dust mask is also advisable.

2. Maintain a Safe Distance: Keep your fingers at a safe distance from the blade and the sharpening tool during the process. It’s easy to accidentally slip and cut yourself, so remaining attentive and cautious is crucial.

3. Use Appropriate Pressure: Applying too much pressure while sharpening can cause the blade to slip and potentially lead to injuries. It could also damage the blade or the sharpening tool. Apply consistent, moderate pressure throughout the process.

4. Secure Your Tools: Ensure the sharpening tool is stable and secure before you begin. This can prevent unnecessary movement or slippage that can result in accidents.

5. Clean the Blade: Ensure you rinse and dry the pizza cutter thoroughly after sharpening. This removes any metal particles that can contaminate your pizza and also prevents rusting.

By following these safety tips, you not only learn how to sharpen a pizza cutter effectively but also safely. Always remember, safety first!

How Often Can You Sharpen a Pizza Cutter?

The frequency of sharpening your pizza cutter primarily depends on how often it is used and the type of surfaces it comes in contact with.

Generally, for a pizza cutter used frequently, it’s advisable to sharpen it once a month to maintain an effective cut and extend its lifespan. For less frequent use, sharpening it every 3-6 months should suffice.

However, remember that each time you sharpen, you’re effectively removing a small amount of material from the blade. Therefore, over-sharpening may lead to reducing the longevity of your cutter.

Techniques Help Maintain a Sharp Pizza Cutter

To help maintain a sharp pizza cutter, it’s vital to adopt good practices that extend its lifespan and ensure optimal performance. Here are a few techniques:

1. Proper Cleaning: After each use, clean your pizza cutter thoroughly to remove any food particles clinging to the blade. Use warm water, mild soap, and a soft sponge to avoid scratching the blade. Ensure to dry it fully to prevent rust. 

2. Regular Honing: Honing aligns the blade’s edge without removing any material, making it a maintenance-friendly technique. Use a honing rod and follow a similar angle that you would when sharpening. This process can be done more frequently than sharpening.  

3. Store Appropriately: Store your pizza cutter in a dry, safe place where it won’t come into contact with other utensils. Clashing of utensils can dull the blade faster. If possible, use a blade guard or case.  

4. Use a Cutting Board: Always use a cutting surface that is blade-friendly such as a wooden or plastic cutting board. Avoid hard surfaces like metal or stone as they can dull the blade.  

By following these techniques, you can prolong the sharpness of your pizza cutter, enabling it to deliver clean, effortless cuts every time.


In conclusion, mastering the art of how to sharpen a pizza cutter is like perfecting a secret recipe – it requires attention, care, and the right techniques. Just as the best pizzas are a blend of quality ingredients, a razor-sharp cutter is the result of consistent maintenance and proper handling.

Remember, every slice of pizza reflects the sharpness of your cutter, and with these tips, you’re now equipped to ensure each cut is as satisfying as the last.

So next time you glide through a hot, delicious pizza, take pride in knowing it’s not just the toppings that made it perfect, but also your finely honed cutter.
