A cable slitter and a wire stripper are both tools used in electrical work, but they serve different purposes and are designed for different tasks. A cable slitter is specifically designed to cut through the outer insulation or jacket of a cable without damaging the internal wires. It is typically used for larger cables, such as coaxial cables, network cables, or multi-conductor cables. The tool often features an adjustable blade that can be set to the thickness of the cable's outer jacket, allowing for precise cuts. Cable slitters are essential for preparing cables for termination or splicing, ensuring that the internal conductors remain intact and undamaged. On the other hand, a wire stripper is used to remove the insulation from individual wires, exposing the metal conductor underneath. Wire strippers are generally used for smaller, single-conductor wires. They come in various designs, including manual and automatic versions, and often have multiple notches or holes to accommodate different wire gauges. The tool grips the wire, cuts through the insulation, and pulls it away, leaving the conductor exposed for connections or soldering. In summary, the primary difference lies in their applications: a cable slitter is used for cutting the outer jacket of larger cables, while a wire stripper is used for removing insulation from individual wires. Both tools are essential for electrical work, but they are not interchangeable due to their specific functions and design features.

A punchdown tool is a hand-held device used in network installations to connect wires to a patch panel, keystone module, or surface mount box. It is essential for terminating twisted pair cables, such as Cat5e, Cat6, or Cat6a, into insulation-displacement connectors (IDCs). The tool consists of a handle and a blade. The blade has two sides: one for cutting excess wire and the other for seating the wire into the IDC. The process begins by stripping the outer jacket of the cable to expose the twisted pairs. Each pair is untwisted and aligned with the corresponding color-coded slots on the IDC. To use the punchdown tool, the installer places the wire into the IDC slot. The tool is then positioned over the wire with the cutting side of the blade facing outward, away from the IDC. Applying firm pressure, the installer pushes the tool down until it clicks, indicating the wire is seated and the excess is cut. This action forces the wire into the IDC's metal contacts, which pierce the wire's insulation to establish a secure electrical connection. Punchdown tools often have adjustable impact settings to accommodate different types of connectors and ensure a reliable connection without damaging the wire or IDC. Some tools also feature interchangeable blades for compatibility with various connector types, such as 66, 110, or Krone. Overall, punchdown tools are crucial for creating stable and efficient network connections, ensuring that data transmission is reliable and minimizing the risk of connection failures.
