  • Klein Tools 935AB4V: My Go-To Torpedo Level

    ByMike Izzo

    After running through countless torpedo levels over the years, I’ve finally found one that doesn’t quit on me. The Klein 935AB4V has become a permanent fixture in my tool bag, and for good reason. That high-vis orange isn’t just for show—when you’re working in dim mechanical rooms or crawl spaces, you can actually spot this thing without playing hide-and-seek with your gear. The magnetic track grabs onto ductwork and conduit like it means business, freeing up both hands when you need them most. What really sold me are those four vial options (0/30/45/90 degrees). Whether I’m checking drain lines or setting up complex duct runs, I’ve got the angle I need without switching tools. The V-groove is clutch for pipe work too. It’s built tough enough to handle real jobsite abuse, and at six inches, it fits perfectly where larger levels won’t.

  • Klein Tools 80020: My Go-To 3-Piece Plier Set

    BySteve

    I’ve been running Klein’s 80020 plier set in my service van for two years now, and these tools have earned their spot in my everyday rotation. As an HVAC tech, I’m constantly cutting wire, gripping sheet metal screws, and working in tight spaces behind air handlers. This three-piece set handles it all without the handles getting slippery or the cutting edges dulling out after a month.

    What sold me initially was the “Made in USA” stamp and induction-hardened blades—not just marketing fluff when you’re cutting through 14-gauge wire fifty times a day. The lineman’s pliers have serious grip strength, the diags cut clean every time, and those needle nose actually fit where I need them. They’re not cheap, but I’m done replacing bargain pliers every six months. Sometimes you just pay for quality once.

  • My Take on Amazon Basics’ 131-Piece Tool Kit

    BySteve

    After fifteen years turning wrenches on everything from residential splits to commercial chillers, I’ve learned that a tool kit’s real test isn’t in the box—it’s on the job site. Amazon’s 131-piece set caught my attention as a potential starter kit for apprentices or a backup for service vans. At this price point, I wasn’t expecting Snap-On quality, but I needed to know: would these tools hold up when you’re troubleshooting a failed compressor at 2 AM? I put this kit through typical HVAC scenarios—tightening electrical connections, swapping contactors, and general maintenance work. The storage case is solid, which matters when you’re hauling gear up ladders and across rooftops. But before recommending it to my crew, I had to dig deeper into build quality and real-world durability.
