Klein 21010-6-SEN: My Go-To Wire Snip for HVAC
After fifteen years in HVAC, I’ve gone through more wire snips than I can count. The Klein 21010-6-SEN finally put an end to that revolving door. These aren’t your typical hardware store snips-the serrated blades actually grip stranded wire instead of pushing it around, which matters when you’re working in tight spaces behind air handlers. The built-in scraper handles wire insulation without reaching for another tool, and that file edge? I use it daily for deburring copper. What really sold me is the free-fall mechanism-it springs open with one hand while you’re balancing on a ladder. Made in USA means something with Klein; I’ve had mine for two years of daily abuse and the blades still bite clean. They’re not cheap, but neither is my time replacing tools that quit.
