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'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'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!).
