I've used those but just couldn't keep 'em handy when I needed them but also had a set of diagonal cutters or electrician's cutters handy and as you know, they don't cut flush, leave a sharp edge, hence the Bic lighter. I also had issues using the flush cutters in tight places where the power was still on (inside traffic signal cabinets) but not with the cutters.I learned, early one, with wire ties to use a flush cutter. No sharp edges at all that way. Radio Shack used to sell a pair for about five bucks. Still have a few hanging around.
I'm a firm believer in folks using what works best for them and what they're comfortable with. I admit, I kinda did it the hard way for 31 years but I'm still here after retiring 14 years ago and have my fingers and both eyeballs (thank you, Lord!).
