I bought a craftsman "heave duty hedge trimmer" that has been awful. It says
it can cut through 3/4 stems, but it has been awful cutting through my ivy.

My neighbor has an old school Craftsman from 20-30 years ago that works
great.

I'm curious if there are any other brands that will cut through stems
greater than this, although all electric ones I've seen say 3/4 at most. Do
I need to buy a gasoline powered one instead ?

Thanks
