The jaws and handles of electronics cutters are usually made from high carbon tool steel, or vanadium steel, which creates significantly harder cutting edges. This gives electronics cutters the strength to cut through resistor wire, memory wire, or thin spring steel wire.
There are also electronics cutters with harder jaws made from tungsten alloy or tungsten carbide, which can be useful for a wide range of industrial and everyday applications.
The jaws of electronics cutters often have additives such as chromium, which help to prevent corrosion.
The sleeves that fit over the handles of electronics cutters are either moulded out of thermoplastics or created by dipping the tool in plastic.
ESD cutters have high-dielectric inner insulation to prevent the tool from building up an electrostatic charge that might damage sensitive electrical components. This insulation is typically made from advanced thermoplastic materials like polyetherimide.
