There are secateurs for your little bits of light chopping and pruning.
Then come the loppers for stuff that’s a bit meatier. Maybe branches that are 20mm or 30mm at the most.
After that my option used to be a chainsaw which is often a bit overkill for some of the stuff that I’d cut with it. But now I have a new option! The Ryobi reciprocating saw. Oh yes.
The first job for the saw was chopping through an ivy stem that was attacking one of my tress. Like a hot knife through butter! Yusssssss
