KNIPEX has released the 16 50 145 SB stripping knife, featuring a ratchet mechanism and multi-cut blade for tough, heavily reinforced cable sheaths.
German hand tool manufacturer KNIPEX has expanded its electrician lineup with the introduction of the 16 50 145 SB Stripping Knife. Designed specifically to handle tough, hard, and heavily reinforced outer cable sheathing, the new hand tool aims to reduce physical strain while preventing accidental damage to the underlying internal conductors.
The tool incorporates an integrated ratchet mechanism combined with a versatile multi-function blade that features three distinct cutting areas. This layout allows sparks and installers to execute both round and longitudinal cuts efficiently through stubborn sheaths that often cause standard utility knives or conventional stripping tools to slip or stall.
Stripping thick outer insulation on specialized industrial or heavy-duty mains cables traditionally carries two main risks: injury from high-force slips and costly damage to core insulation. The inclusion of a ratchet drive allows the blade to advance incrementally through dense materials, giving the user controlled leverage rather than relying on raw wrist force.
Furthermore, the three-zone blade geometry provides designated cutting edges tailored to specific slicing motions. This design helps maintain a clean cut edge without digging into the underlying wire structure, an essential factor when preparing cables to standard regulatory specs.
What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?
For commercial electricians and site contractors who regularly deal with armored, tough rubberized, or heavy-duty distribution cables, this tool offers a purpose-built alternative to standard hooked utility blades. While standard trimming knives remain dirt cheap at retail, they wear quickly and present higher slippage risks on rigid insulation. Investing in specialized KNIPEX cable prep kit generally carries a premium retail price point, but it directly cuts down on wasted cable tail ends and prep time. Buyers should expect stock to roll out across major UK electrical wholesalers and tool stockists shortly, making it a key trade purchase if tough cable prep is a daily site requirement.
