Insulated Cable & Duct Sheathing Knife - 1000V Rated Stainless Steel with Curved Blade (KN-200INS)

Ships direct from the manufacturer. Please allow up to 10 business days, though it often ships sooner.

A sheathing knife has two jobs that pull against each other: cut through the jacket, and stop before the conductor insulation under it. The Jonard Tools KN-200INS does both with a curved stainless steel blade that has a narrow guide shoe on its tip, so the shoe rides between the jacket and the conductors and keeps the edge from reaching the insulation inside. The blade is sharpened on both sides, so it slits by pushing or by pulling, whichever the position of the cable allows, on cable and duct jacket alike. What sets it apart from an ordinary sheathing knife is the handle: a dual-component insulated grip rated for work on live equipment up to 1000 V and compliant with DIN EN 60900 VDE 0682-201:2013-04, the standard for insulated hand tools. The soft grip makes a long slit easier on the hand, and a safety cap and tethering hole come with it for transport and storage.

Features

• 1000 V insulated handle. Dual-component handle rated for use on live equipment up to 1000 V, compliant with DIN EN 60900 VDE 0682-201:2013-04.
• Dual-sided curved blade. Ultra sharp and sharpened on both sides, so it cuts cable or duct jacket by pushing or pulling the tool through the cable.
• Guide shoe on the tip. A narrow shoe that keeps the blade from damaging the conductor insulation under the jacket.
• Stainless steel blade. 1.5 in (3.81 cm) long, resistant to corrosion in a damp vault or an outdoor box.
• Soft-grip ergonomic handle. Comfort over a long slit, and easier control of the cut.
• Safety cap and tethering hole. Included cap for the blade, and a hole for a lanyard.

Where It Fits

It suits electricians slitting the jacket on NM, SER, and SE cable at the panel and on tray cable and multi-conductor control cable in a gear room, utility and industrial electricians who work in or near energized equipment and need every hand tool on the bench to be VDE rated, telecom and fiber technicians slitting duct and cable sheath where a knife is the right tool and a slitter isn't, solar installers opening the jacket on large DC conductors and conduit runs, anyone who has nicked a conductor with a utility knife and wants a blade that can't reach it, and a tool kit being built or audited to a 1000 V insulated standard. For a knife without the insulated handle, the UKN-3 utility knife is the general-purpose option; for round cable and duct where a fixed-depth cut is better than a knife, the Jonard slitters and ring tools.

Good to Know

The 1000 V rating is for the handle, and it holds only while the handle is intact: inspect it before each use for cuts, cracks, or wear through the outer layer into the inner one, since a dual-component handle shows damage by color, and retire the tool if the inner layer shows. The blade is not insulated, and the rating doesn't make the work safe on its own; de-energize and verify where you can, and where you can't, the insulated handle is one layer in a live-work procedure that includes gloves, PPE, and the rest. To slit, set the guide shoe under the jacket at the cut end, hold the cable so the blade runs along its length, and push or pull the knife through the jacket in one steady motion, letting the shoe ride on the conductors; the shoe is what keeps the edge off the insulation, so keep it under the jacket and don't tilt the blade into the cable. For a ring cut, score around the jacket with the curved edge and flex the cable to finish rather than cutting through. The blade is double-sided and sharp on both edges, which means there's no safe edge to push against with a finger; cut away from the hand holding the cable. Put the safety cap on before the knife goes in a pouch, and tether it on a lift or a ladder. Stainless steel resists rust but not neglect; wipe it dry after a wet job. This is a sheathing knife; it isn't a utility knife and shouldn't be used on cardboard, drywall, or anything that will dull a blade meant for jacket.
