Klein Tools J2159CRTP Side Cutting Pliers - High-Leverage Hybrid

Our review of the Klein Tools J2159CRTP finds it best suited for electricians, contractors and serious DIYers who need one durable tool to strip, crimp and cut. The single biggest reason to buy is its high-leverage, induction-hardened cutting edges combined with a built-in fish tape puller that protects cable during pulls; that mix of cutting power and thoughtful utility makes it a practical daily tool rather than a specialty novelty.

Key Features

• Strip, crimp and cut: Combines a wire stripper, crimper and side cutter so a single plier handles multiple common tasks on the job.
• High-leverage design: Provides improved mechanical advantage for easier cutting of hard wire and reduced hand fatigue during repetitive use.
• Induction hardened knives: Full-length hardened cutting edges deliver stronger cutting performance and longer edge life on tough material.
• Fish tape puller channel: Built-in channel lets you pull steel fish tape without damaging conductors, preserving cable insulation when fishing runs.
• Wide knurled head: The broad textured head easily grabs and twists wires for secure bends and combines gripping and cutting in one motion.
• Bolt shears and crimper: Convenient holes shear common machine screws and crimp non-insulated connectors, reducing the need to carry extra tools.

Who It's For

The J2159CRTP is aimed at professional electricians, maintenance techs and homeowners who perform frequent wiring work and want a single, durable plier to replace several lighter tools. It excels in residential and light commercial wiring where stripping 10-14 AWG solid and 12-16 AWG stranded wire is a common task.

Those who should look elsewhere include users who need heavy-duty dedicated cutters for large gauge cable beyond the described wire ranges or specialists who prefer separate precision tools for crimping and cutting; this hybrid is optimized for versatility rather than niche heavy industrial duties.

Pros & Cons

• Durable induction-hardened cutting edges provide reliable cutting performance on hard wire.
• Multifunction design replaces several tools for everyday electrical tasks, saving space in a bag.
• Wide knurled head and fish tape channel add practical utility for pulling and twisting wires without damage.

Cons

• Not intended as a replacement for heavy-duty cutters on very large gauge cable, so performance is limited to the specified wire ranges.
