– When using a sharp craft knife or scissors, make sure to use slow, deliberate cuts. Foam can be easily damaged if it is cut too quickly.

– If you need to make curved cuts, consider using a utility knife with a new blade. Slowly draw the blade around the curve of your template in order to create clean, precise cuts.

Tools of the Trade

If you want to cut foam like a pro, there are a few tools of the trade you should know about. A hot wire foam cutter is a must for anyone serious about cutting foam. A hot wire foam cutter will allow you to make precise cuts with little to no effort. You can also use a utility knife or an electric carving knife, but a hot wire foam cutter is the best option if you want clean, professional looking cuts.

Electric Knife

An electric knife is a kitchen tool that is used to slice through food with ease. It consists of two blades that are serrated and move back and forth quickly, making it ideal for cutting through tough or thick cuts of meat, bread, and even foam.

When cutting foam, an electric knife can be very helpful in getting clean, precise cuts. It is important to use a sharp blade when cutting foam, as a dull blade will crush the foam instead of slicing through it. In addition, it is important to use a steady hand whenCutting Foam With an Electric Knife guiding the electric knife through the foam, as if the blade wobbles it will create uneven cuts.

Hot Wire Foam Cutter

A hot wire foam cutter is a device used to cut polystyrene foam and other types of foam with a heated wire. The hot wire foam cutter is a simple but versatile tool that can be used for a wide variety of projects, from model making to packaging design.

The hot wire foam cutter consists of two main parts: the power supply and the cutting head. The power supply provides the electricity needed to heat the cutting wire, while the cutting head contains the wire and guides it through the foam.

To use a hot wire foam cutter, simply turn on the power supply and pass the cutting head through the foam. The heat from the cutting wire will quickly slice through the foam, allowing you to create clean, straight cuts.

Hot wire foam cutters are available in a variety of sizes and shapes, so you can find one that’s perfect for your specific needs. Whether you’re looking for a compact cutter for small projects or a larger cutter for industrial applications, there’s a hot wire foam cutter out there that’s right for you.

Styrofoam Cutter

A Styrofoam cutter is a tool used to cut pieces of Styrofoam into various shapes and sizes. They are often used for craft projects, model making, and packaging. Styrofoam cutters come in a variety of styles, but all operate on the same basic principle: they heat up a wire or blade that then melts through the foam.

The most basic type of Styrofoam cutter is a wire cutter. These consist of a simple wire that is heated up and then drawn through the foam. Wire cutters are inexpensive and easy to use but produce very rough cuts. For this reason, they are not recommended for precise cutting applications.

Blade cutters are slightly more expensive but produce much cleaner cuts. Blade cutters work by heating up a metal blade and then pressing it against the foam. The blade will quickly cutting through the foam, leaving behind a clean edge.

There are also rotary cutters available that work similar to blade cutters but use a spinning cutting head instead of a stationary one. Rotary cutters are great for quickly cutting large pieces of Styrofoam but can be more difficult to control than blade cutters.

When choosing a Styrofoam cutter, it is important to consider what type of cuts you will be making and how precise they need to be. For general purpose cutting, a wire cutter or blade cutter should be sufficient. For more precise applications, such as model making, a rotary cutter may be necessary.

Cutting Techniques

Cutting foam can be a tricky business. If you don’t have the right tools or techniques, you can end up with a big mess. In this article, we’ll show you how to cut foam like a pro. We’ll cover the different types of foam, the best tools to use, and some tips and tricks to help you get the perfect cut every time.

Straight cuts

One of the most basic yet essential cuts for any barista is the straight or diagonal cut. This cut is used to remove a portion of foam from the top of a pitcher or cup, creating a level surface for pouring.

There are two ways to execute a straight or diagonal cut:

-With your non-dominant hand, place your thumb on the side of the pitcher just below the foam line. Use your other hand to hold the razor at a 45-degree angle and make a single, sweeping motion away from your body.


-With your dominant hand, hold the razor at a 45-degree angle and make a single, sweeping motion away from your body. Use your other hand to stabilize the pitcher by placing your thumb on the side of the vessel just below the foam line.

Curved cuts

Curved cuts are the most difficult type of cuts to execute because the blade has to both push and pull in order to create the cut. Start by pinching the foam at the point where you want the curve to start. Slowly begin to guide the blade along the foam while maintaining pressure with your fingers to create a clean cut. Try not to apply too much pressure, as this can cause the blade to slip and result in an uneven or jagged cut.

Freehand cuts

You don’t need any fancy tools to make freehand cuts. A sharp knife and a steady hand are all you need. For this method, it’s best to start with a block that is at least 2” thick. This will give you enough material to work with and will also help to keep your cuts more precise.

Start by scoring a line into the block using a sharp knife. You can make this line as straight or as curved as you like. Just be sure that it is not too deep – you don’t want to cut all the way through the block.

Once you have scored your line, start making shallow cuts along the line using a sawing motion. Work slowly and carefully so that you don’t veer off course. Continue making shallow cuts until you have cut through the entire block.

Tips and Tricks

Foam is a versatile material that can be used in a variety of projects. It is relatively easy to cut, but there are a few things you should keep in mind to get the best results. In this article, we will go over some tips and tricks on how to cut foam like a pro.

Use a cutting board

Cutting foam can be a bit tricky, but with a few tips and tricks, you can cut foam like a pro! Here are a few things to keep in mind when cutting foam:

-Use a cutting board: A cutting board will help protect your countertop or table from cuts. It also provides a stable surface for cutting foam.
-Use a sharp knife: A sharp knife will make cutting foam much easier. If you find that your knife is dull, you can use a utility knife or box cutter to make the cuts.
-UseSandpaper: If you want to create a smooth finish on your foam, you can use sandpaper to sand down the edges after you’ve cut them.

Score the foam first

Scoring the foam first will help you get nice, clean cuts that are less likely to crumble. To score the foam, use a sharp knife to make shallow cuts in the surface of the foam. Be sure to only cut through the top layer of the foam—you don’t want to cut all the way through to the cake beneath.

Once you’ve scored the foam, use a sharp serrated knife to cut through the scored lines. You can saw back and forth gently, or you can hold the knife in one place and twist it back and forth to create a curved edge.

If you’re having trouble cutting through the foam, try heating up your knife with a blow dryer before cutting. The heat will help to soften the foam and make cutting easier.

Use a sharp blade

To get a clean cut, it’s important to use a sharp blade. A dull blade will create jagged edges and may even tear the foam. If you’re not sure if your blade is sharp enough, test it on a piece of scrap foam before cutting the pieces you need.

It’s also important to use a straight edge when cutting foam. A ruler or a T-square can help you keep your cuts straight and prevent the foam from slipping while you cut it. If you don’t have a straight edge, you can also use a string or strip of tape as a guide.

Finally, make sure to protect your work surface when cutting foam. Foam can damage surfaces like wood and Formica, so it’s a good idea to lay down a sheet of cardboard or poster board before you start cutting.


That’s it! You now know how to cut foam like a pro! Just remember to always use a sharp blade, and make sure to keep your cuts straight and clean. With a little practice, you’ll be able to create perfect foam shapes every time.
