I'm one of those people who for yonks has used side cutters to chomp through larger cables in several munches… with prices like this one is now, time to do it proper. Knipex webpage says it will cut up to 20mm diameter. No personal experience yet!
From what I saw online, it seems to be cleaner than the stepcut shears. I don't really know though. However if it's of interest the small stepcut is only a little more at $39.55 delivered https://www.amazon.com.au/Knipex-StepCut-160-95-11/dp/B0863B…. Knipex webpage says it will cut 14mm diameter.
this will pay for itself in no time with sporting field lighting cables!
