  • Klein Tools DK06 Duct Knife: My Go-To Blade

    BySteve

    I’ve been running HVAC calls for over a decade, and I’ve gone through more duct knives than I care to count. Most either dull out after a few jobs or feel like they’re going to snap in half when you’re wrestling with dense board. The Klein Tools DK06 changed that for me. This thing cuts through flex duct like it’s not even there, and when you hit rigid board, the serrated blade actually grabs instead of sliding off. The grip doesn’t get slippery when your hands are sweaty, and at the end of a long day, my hand isn’t cramping up. I keep mine on my belt in the included sheath, and it’s held up to daily abuse for two years now. It’s not the cheapest option out there, but it’s the last duct knife I’ve had to buy.

  • My Take on the Klein Tools Electrician’s Knife

    BySteve

    I’ve been carrying the Klein Tools Electrician’s Pocket Knife for six months now, and it’s become one of those tools I actually notice when I forget it. The stainless steel blade holds an edge better than I expected—I’ve stripped countless Romex jackets and trimmed wire insulation without needing to sharpen it yet. What really sold me is the deep-carry clip. It sits low in my pocket and doesn’t snag on everything like my old knife did when I’m crawling through tight attic spaces or squeezing behind condensers. The lanyard hole is a nice touch for those rooftop jobs where dropping a tool means a long walk down. It’s not fancy, but Klein knows what electricians and HVAC techs actually need. Solid everyday carry that just works.
