Here are some key points about insulated tin snips:

1. Insulation: The handles are coated with a non-conductive material, usually plastic or rubber, to provide electrical protection. This helps prevent electrical shock if the tool accidentally comes into contact with live wires.

2. Types: Tin snips come in various types, such as straight-cut, left-cut, and right-cut, depending on the direction of the cut you need to make. Insulated versions will have these same variations.

3. Blades: The blades are typically made of high-carbon steel or another durable material to handle tough materials and provide clean cuts.

4. Usage: They're used for cutting through sheet metal, aluminum, and other similar materials. The insulated handles make them suitable for use in electrical work or other scenarios where there's a risk of encountering live wires.

5. Safety: Always check the insulation for any signs of damage before use, and ensure that the insulation is rated for the voltage you might encounter.

If you work with sheet metal and need an extra layer of safety, insulated tin snips are a practical choice.
