Jonard KN-7 Cable Splicing Knife 1 3/4 In Blade

Jonard KN-7 Splicing Knife

The Jonard KN-7 is a cable splicing knife built for electricians and technicians who strip and splice conductors daily. Its 1 3/4 inch steel blade handles insulation and jacketing on communication and power cables. The thermoplastic rubber grip resists slipping when hands are wet or gloved. This tool suits professional maintenance and installation work.

Installation and common issues

No installation is required; the knife is ready to use straight from the package. The blade ships extremely sharp, so the most frequent issue is accidental cuts during the first few uses. Always cut away from your body and wear cut-resistant gloves until you are accustomed to the edge. Store the knife with a blade guard or in a pouch to protect the edge and prevent injury.

Pre-purchase checks

Verify that a fixed-blade splicing knife matches your job requirements; some crews prefer folding or retractable models for pocket carry. Confirm that the 6 1/4 inch overall length fits your tool belt or bag. Note the California Proposition 65 warnings regarding chemicals known to cause cancer and reproductive harm. Buyers who need a dedicated insulation stripper or a multi-function electrician’s knife should look at other tool types.
