The Knipex 90 10 165 BKA CutiX Universal Snap Knife is a professional utility knife built for controlled cutting with snap-off blades. This is a utility knife designed for general cutting tasks like cardboard, plastic, sheeting, and trim materials. Model Number: 90 10 165 BKA. If you want a hand tool that gives you more support than a basic box cutter, this is the point of the design.

The standout feature is the stabilization bar. On a normal snap knife, the blade can flex when you push hard into dense material. Here, Knipex adds a separate slider for the stabilization bar and another for the blade, so you can set the knife up for the cut instead of fighting the blade. That matters when you are scoring thicker stock, trimming tough packaging, or making repeat cuts where control is more important than just getting the blade out farther.

The body is made from lightweight magnesium, which keeps the knife easy to carry without feeling flimsy. Non-slip gripping surfaces help when your hands are dusty or gloved, and the overall 6-1/2 inch size is compact enough for pouch carry without giving up usable reach. At 0.243 lbs, it stays light in the pocket but still feels like a real jobsite tool, not a throwaway knife.

Knipex also got the day-to-day details right. Blade changes are tool-free with a push-button release, and the knife accepts standard 18 mm snap-off blades, so you are not locked into some odd replacement format. Two spare blades store in the handle, which is one of those small features that saves time because the backup blades are already with the tool when the edge goes dull.

This knife also includes a tether attachment point for use with the KNIPEX Tethered Tools System. For anyone working on ladders, lifts, mezzanines, or finished spaces below other trades, that is a practical feature, not a gimmick. It gives you another option for keeping the knife secured when drops are not acceptable.

The Knipex 90 10 165 BKA CutiX Universal Snap Knife makes the most sense for contractors, electricians, HVAC techs, remodelers, warehouse crews, and serious DIY users who cut a lot of material and are tired of flexy snap knives. If your work regularly involves cardboard breakdown, sheet goods, vapor barrier, roofing wrap, plastic strapping, or general jobsite trimming, this utility knife earns its keep by giving you better control and a more durable housing.
