A hacking knife is almost exactly what it sounds like — a knife used to hack through the hard outer sheath on electrical cables or remove old putty from windows. You’ll find them mainly in England, but they’re also available state-side and can come in handy in lots of projects around the home and shop. We’ve particularly used them to scrape and cut stubborn sheilding from cable.
The steel blade is 1⁄4″ thick with a full-tang. (The “tang” is the back side of the blade. Blades with a “full-tang” are almost wedge-shaped at the back, whereas knifes without a “tang” are thin all the way back.) It’s crafted with enough heft to take a hammer pounding from the backside and force the edge through all manner of materials such as PVC, bricks, wood, and even sheet metal — though if you’re using it for sheet metal you’d better bring a large hammer.
Street pricing for a set like this one starts at around $18
