This is a chisel knife designed for cable splitting, deburring, and light chisel-style work. Model Number: DK-TN80.\u003c\/p\u003e\n      \u003cp\u003eThe main reason this knife stands out is the hollow-ground blade. On THWN, THHN, and NM cable, that blade geometry is built to split material smoothly instead of binding and dragging. If you spend time opening jacketed wire or cleaning up insulation without nicking what matters, that design is the whole point. Tajima also adds a deburring groove on the blade, so you can clean up rough cut surfaces without reaching for another tool.\u003c\/p\u003e\n      \u003cp\u003eThis is not just a utility knife with a fancy shape. The blade has a chisel-like tip for added versatility, which gives you more control when scoring, scraping, or doing detail work where a standard straight knife is not the best fit. Tajima pairs that with a steel blade and hard chrome plating for durability and edge protection in real jobsite conditions.\u003c\/p\u003e\n      \u003cp\u003eThe full-tang construction matters because it changes how the tool feels under load. When a knife is meant to be tapped or used like a light-duty chisel, you want the blade and handle working as one piece. Tajima built the DK-TN80 with a hammer-ready full-tang blade and an end cap designed to prevent metal-to-metal contact. In plain terms, it is made to take jobsite abuse better than a basic electrician's knife.\u003c\/p\u003e\n      \u003cp\u003eDay-to-day usability is solid too. The non-slip elastomer grip helps keep the handle planted in your hand when conditions are dusty or when you're working with gloves. There is also a safety rope mounting hole, which is a small detail that makes sense for ladder work, overhead work, or any situation where dropping a hand tool is a problem. A blade protector is included, which makes storage and transport safer and helps protect the edge between uses.\u003c\/p\u003e\n      \u003cp\u003eThis Tajima chisel knife makes the most sense for electricians, maintenance techs, and construction pros who want a fixed-blade hand tool that can handle cable work and small prying or striking tasks without switching tools constantly. If your work is mostly precision cable prep and general jobsite utility, this is a more purpose-built option than a standard pocket knife. If you want a folding knife or a tool meant for heavy demolition, this is not that. It is a specialized electrician's chisel knife built for controlled cutting, clean edge prep, and hard everyday use.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eCut Cable With More Control\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"row\"\u003e\n        \u003cdiv class=\"img\"\u003e\n          \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/2026052038_1.jpg\" alt=\"Tajima VARIX Chisel Knife full product view showing the hollow-ground blade and grip, designed for cable splitting and electrician jobsite work\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThis blade shape is built for electricians who need cleaner, more predictable cuts on common cable types.
