The variety of cable strippers represented in this section is a function of the many types of cable you can work with, various costs of the cable strippers, and versatility of the tools.
1. Twisted-Pair Strippers
Strippers for UTP, ScTP, and STP cablesare used to remove the outer jacket and have to accommodate the wide variation in the geometry of UTP cables. Twisted-pair cables can have irregular surfaces due to the jacket shrinking down around the pairs. Additionally, the jacket thickness can differ greatly depending on brand and flame rating. The trick is to aid removal of the jacket without nicking or otherwise damaging the insulation on the conductors underneath.
the outer jacket, making this an effective approach.

If you use a regular set of lineman’s pliers to snip through coaxial and twisted-pair cables, or even use them for fiber optic cables, you will find cutting through the aramid yarns used as strength members can be difficult, and dull your pliers quickly. Aramid is used in optical fiber cable to provide additional strength.

crimper. Modular plugs for cables with solid conductors (horizontal wiring) Note are sometimes different from plugs for cables with stranded conductors (patch cords). The crimper fits either, and some companies market a universal plug that works with either. Make sure you select the proper type when you buy plugs and make your connections.

Coaxial-cable crimpers also are available either with changeable dies or with fixed-size crimp openings. Models aimed strictly at the residential installer will feature dies or openings suitable for applying F-type connectors to RG-58, RG-59, and RG-6 series coax. For the commercial installer, a unit that will handle dies such as RG-11 and thinnet with BNC-type connectors is also necessary.>>Punch-Down Tools
conductor in the IDC termination slot is a punch-down tool.
A punch-down tool is really just a handle with a special “blade” that fits a particular IDC. There are two main types of IDC terminations: the 66-block and the 110-block. The 66-block terminals have a long history rooted in voice cross-connections. The 110-block is a newer design, originally associated with AT&T but now generic in usage. In general, 110-type IDCs are used for data, and 66-type IDCs are used for voice, but neither is absolutely one or the other. Different blades are used depending on whether you are going to be terminating on 110-blocks or 66-blocks. Although the blades are very different, most punch-down tools are designed to accept either. In fact, most people purchase the tool with one and buy the other as an accessory, so that one tool serves two terminals.
1.Punch-down tools are available as nonimpact in their least expensive form. Nonimpact tools generally require more effort to make a good termination, but they are well suited for people who only occasionally perform punch-down termination work.
