Tough! These things are nasty Bought these for a specific use purpose
So far, I have made only a few cuts with these
They take a fair bit of effort, but they do the job
Cannot testify about using them with thicker cable, but I have used cable cutters from tiny (bicycle brake and gear changer cables) up to this size for many years
This cutter is rated for: 1/2 wire rope, 7/16” ACSR and 1” copper-aluminum cable, as is shown on a sticker on the tool
I wish they were made in America, but so far they've been durable
