What is a Pizza cutter?

What is a Pizza cutterA pizza cutter is also known as a Rozzapreti in Italian. It is a tool used to cut a pizza, a calzone, a sandwich, or any other round food. You can place it on the pizza’s crust after removing it from an oven or a stovetop. This tool prevents hand burns from the heated pizza crust. 

It consists of a solid handle with a wheel attached to its end, which usually has a trough or blade. A pizza cutter is a popular alternative to a knife and fork. It is operated by hand easily.

By design, pizza cutters resemble more extensive versions of the wheel of a railroad locomotive. The pizza wheel rotates on a central axle and has slicing blades running parallel to the wheel’s edge. Pizza wheels can be two-wheeled (dough cutter), four-wheeled (pizza scissors), or six-wheeled.

How To Sharpen A Pizza Cutter

Pizza cutters need to be sharp to slice the dough into perfectly even slices. The best way to ensure that your pizza cutter remains sharp is to maintain its edges. Well-sharpened blades allow the gooey cheese and stringy, delicious sauce to slide right off of your pizza in one bite. Here are the various methods to use:

Using a Wet Stone

Why use a wet stone? Water creates a slurry of aluminum oxide that removes steel at much higher rates than dry sand can. Water is also needed for lubrication to allow the water-stone slurry to flow freely.

Material Needed:

  • Protective glove
  • Polishing spray
  • Wet stone

Step 1: Wet the blade with cold water before starting.

The first thing to do is wet the blade with cold water before grinding on the available wet stone, as this protects the edge from heat damage and makes sharpening easier. 

Sharpening is completely painless when you wet the blade with water before starting to sharpen. It prevents heating of the edge, which softens the blade making it less resistant to penetration by the abrasive material. Using oil will cause heating, so water is the best to use.

Water is used with the stone to keep cool throughout sharpening, but water must keep it at the correct levels.

Step 2: Grind the cutter against the stone.

Sharpen one side of the blades, then sharpen the other side with the wet stone to grind away the carbides on the cutting wheel, leaving a consistent surface. The process is straightforward, but be careful! If you are holding the pizza cutter in your hands when you grind it down against the stone, there is a chance that it will slip out of your hand. 

 A thick wet stone is ideal for sharpening a pizza cutter as it will keep the cutter level as you cut, and it will create an edge that you can feel and see. 

Step 3: Apply a polishing compound with a cotton cloth after sharpening

Apply a polishing compound with a cotton cloth to remove roughness, and finally, clean the knife thoroughly. Polishing compound is beneficial for removing chips and nicks from plane blades. It helps restore the bright finish of blades and irons. When applied with a polishing cloth, it removes rust and corrosion as well as old surface discoloration.

Step 4: Test what you have done

After applying the polishing compound on the blades, run it swiftly through a paper; if the paper starts tearing at the point where the blade touches it, congrats! Grab a rag and apply some oil to your newly sharpened blades or tools before sliding them back into their cases. The oil helps protect the metal from oxidizing.  

Using Diamond Sharpening Stone

Diamond Sharpening StoneDiamond Sharpening Stone is used by top experts and can sharpen anything from a tomahawk to a chainsaw. Wherever you may be, this tool will keep your tools in good condition.

Step 1: Take apart the pizza cutter wheel and remove the blade

Remove the blade from the cutter wheel and then hone the knife into a sharper edge that cuts more easily through tough pizza dough.

Step 2: Grind the pizza cutter with Diamond Sharpening Stone

 Move the blade counterclockwise on the diamond stone to achieve a sharper edge after grinding

Step 3: Use a polishing compound to remove any scratches on the surface of the blade

After sharpening the blade with the stone to clean the edge before fixing it back with the cutter, use a polish compound on it to remove any scratches on the blade surface due to the grinding.

Lubricate the blade steel regularly to prevent any future rust.

How to sharpen a mezzaluna

Use a diamond sharpening steel (or Waterstone) to sharpen your mezzaluna. Be sure to keep the angle consistent with the blade’s edge on each side of the mezzaluna. Once you have created sharp edges on both sides of your mezzaluna, you can use it to chop your ingredients.

Always inspect the edge of the mezzaluna blade for signs of chipping or cracking that may weaken it and cause a roughness that will hamper cutting efficiency. It is a specialty knife with a rounded blade that looks like the half of a scimitar. It is perfect for chopping, mincing, and carving soft fruits and vegetables. Having the right tools that are sharp makes all the difference when using a mezzaluna. To use one, you must sharpen it.

Taking care of your mezzaluna is easy. After each use, simply place the mezzaluna blade down (hollow side up) on a clean, dry surface and gently tap the base of the handle with the back of a spoon. This will cause any trapped garlic or herbs that are in the gap to fall out. If you find that this gap is getting plugged up over time, you can also clean it by placing warm water and a little bit of soap down inside and mixing it around with your fingers.
