Some people have work projects that uses foams and they need to cut and shape them according to what they need it for. Using an ordinary blade, cutter, saw or any sharp tools is not advisable because these materials might get deformed due to their texture. That is why a specialized tool is needed for doing this task.

This device is comprised of thin taut metal wire that are made of stainless steel usually or nichrome. An electrical resistance will then heat that handheld foam saw which results in having the material vaporized even before the wire makes contact to it. These devices can be bought from commercial stores or be created yourself in accordance to your needs and preferences.

Two kinds of wires are used that are known as tensioned and preformed for this task. Preformed ones are manually, or with the use of pliers, shaped to certain forms and has a handle used by operators in guiding through the foam. This would allow numerous copies to be created by you of identical patterns that is a big advantage when a project requires this.

The latter type is tightly held by a frame that has springs and people usually use stainless steel with single strand in this rather than nichrome. Homemade ones use leader wire used for fishing or musical instrument strings because of their inexpensiveness and availability. Those commercially made though prefer nickel based alloy wires.

Under this kind, various types of cutters are there which depends on the structure and purpose they specifically have. Handheld uses short strings and operators could easily hand them to cut foam into something they need. This type is what people commonly create by themselves at home due to their simplicity which anyone could make.

Simple manual table cutters could either be vertical or horizontal and uses the table for securing or to guide the foam. Hobbyists utilize vertical one in cutting complex small shapes like letters which are prismatic only. Usually, the horizontal is for construction as well as packaging where both sides have tracks that the wire is being attached to and have an up and down movement for cutting exact sizes.

Template guided ones with an attached string to templates on both sides of foam block and guides it to form a prismatic or tapered shape. This can be manually moved by hands or using pulley mechanism with each end of the string connected with weights. The accuracy that the created patterns have depends on their templates and the operator skills.

Push through slicer have parallel tensioned wires attached to vertical or horizontal frames with even spaces between them. Large blocks are either pushed through on rollers or with gravity and are sliced into sheets sold for construction work. The strings are adjustable and replaceable which allows different thickness to be produced.

The computer numerically controlled ones guide the tensioned wire on each side of that block in forming tapered or prismatic shapes. Different components that the device has affect accuracy including the tightness of the attached string. Lathe attachments are being offered for making possible the cutting of spiral shapes.
