I've owned no less than a dozen of these tools and used them for my wiring business for the past 6 years. On Nov 19, 2017 I purchased another pair, noting that the design of the tool had changed yet part number was the same. The new tool was surprising total junk. It had trouble cutting 18 AWG wire (see pic). Wiring is our business and these used to be the best tools: they were sharp, effective and pretty ergonomic. They are our go-to diag cutters. However, they are not the same product anymore. Look at the picture - the cutting edges don't even line up. I don't know if I just got a bad pair, but even that says something about poor quality control. They are going back as soon as I can get there.
