How does a hot wire cutter work?

hotwire foam cutter is a tool used to cut polystyrene foam and similar materials. The device consists of a thin, taut metal wire, often made of nichrome or stainless steel. A thicker wire preformed into a desired shape, heated via electrical resistance to approximately 200 °C (390 °F).

How do you cut foam padding? How do you cut polystyrene blocks?

Before you cut foam, always make sure your work surface is flat, stable, and won’t be damaged by cutting through the foam with the knife. If you choose to use a carving knife, use a gentle back-and-forth sawing motion and let the blade work through the sheet.

How do you smooth out Styrofoam?

  1. Cut or trim your Styrofoam project pieces.
  2. Cut a 2-inch square scrap piece of Styrofoam. Rub the cut edge of the scrap piece against the cut edges of the Styrofoam project pieces. This will sand and smooth the rough-cut edges.
  3. Rub the scrap piece of Styrofoam against sharp corner edges of the cut Styrofoam project pieces to round, bend, taper, and shape them.

How do you cut foam core cleanly?

The most important thing – a very sharp blade. Once the blade begins to dull, it will start tearing through the foam instead of slicing it cleanly. I use a metal ruler as a guide to cut along straight lines. Get one with a cork backing, so it doesn’t slide around on you while cutting. Using a proper cutting mat under the foam core also helps keep it from moving and helps your blades stay sharp longer.

Does Styrofoam dull knives?

Regardless, after cutting several linear feet (maybe in the neighborhood of 5-10?), the knife blade begins to dull rapidly and no longer produces nice cuts but begins to tear the foam instead. You can always sharpen your blade on a stone, but in short order, it will again dull and tear.

Best Hot Knife Foam Cutter – Buyer’s Guide

How to Properly Cut Styrofoam

If you are not sure how to go about cutting styrofoam, follow the next tips:

How to Cut Styrofoam Manually

1. Use a Cutter/Blade

If you are attempting to carve small shapes out of styrofoam, you can use a small cutter or blade by waxing it up. This will prevent the styrofoam from becoming damaged. To do so, before cutting, run the blade along with an old candle. Make sure to use a white candle, however, to avoid coloring the styrofoam.

2. Use Dental Floss

Best Styrofoam Cutters - Reviews & Buyer’s GuideTo make short straight lines through styrofoam, try using dental floss. First, lay the foam down with the floss beneath it. Then, align the floss according to the direction in which you want to cut the styrofoam. Finally, place on hand on the styrofoam sheet and pull the floss towards you.

3. Use Cookie Cutters

If you are using a thin piece of styrofoam, you can use cookie cutters to create specific shapes. With it securely placed on a flat surface, press the cookie cutter into the styrofoam sheet until it punches through it.

How to Cut Styrofoam Using Electric Tools

1. How to Cut Thick Pieces of Styrofoam

Best Styrofoam Cutters - Reviews & Buyer’s GuideIf you are trying to cut a thick styrofoam piece quickly and effectively, your best bet is to use an electric knife. Please take into account, though, that they are only effective for making straight cuts.

2. How to Cut Through Styrofoam

When you attempt to make a hole through styrofoam without damaging it, the best option is to use a hot knife like the ones reviewed in this guide. Easy to handle and precise, this type of tool is very effective at making cutouts.

3. How to Make Smooth Cuts on Styrofoam

Without a doubt, a countertop (tabletop) wire cutter is the best choice when it comes to making complex shapes out of styrofoam. Apart from allowing great detail, this type of styrofoam cutter is great at smoothing out the styrofoam’s freshly cut edges as it cuts, resulting in smoother, better-defined shapes.

How to Make Advanced Cuts On Styrofoam

1. How to Reduce the Chance of Breakage

Best Styrofoam Cutters - Reviews & Buyer’s GuideWhen cutting styrofoam, always try to keep a steady and even pressure as you slice through. If you do this correctly, you will greatly reduce the chances of breaking or crushing the foam. As a bonus, using slow and steady motion can help the tool cauterize the styrofoam as it cuts, resulting in smoother edges and more precision overall. Furthermore, it will minimize the formation of debris.

2. How to Cut Out Shapes From Styrofoam

When attempting to cut a depression in styrofoam, always start at the center of the sheet. If possible, use a pencil to draw a line around the area you want to cut out first. Then, make a vertical incision into a single spot on the material. After that, begin moving the tool to cut out the shape you want.

3. How to Cut Channels On Styrofoam

Best Styrofoam Cutters - Reviews & Buyer’s GuideWithout a doubt, the best way to cut channels on styrofoam is to use a long hot knife. If possible, use a serrated one. Before starting to cut, mark the line where the channel will go using a pencil or marker.

Then, align the wire or blade vertically with the line and begin applying pressure slowly and steadily.

4. How to Cut Styrofoam Balls in Half

Whenever you need to cut a styrofoam ball in half, it is best to use a countertop hot wire cutter. Before cutting, though, make sure to trace a line along the equator of the ball. Often, this line has already been marked by the manufacturer. If that is the case, use that line. Once you are sure about the line you want to make, take the ball and align its equator line vertically with the cutting wire. Then, push the ball slowly as steadily towards the wire until it cuts through.


Without a doubt, a styrofoam cutter is one of the most important tools you can have when building a modeling project from scratch. Hopefully, this buyer’s guide will help you choose the perfect styrofoam cutter for your personal needs.
