I've got hundreds of hours doing clearing work (early years I used a machete- was VERY effective): most is clearing invasive blackberries (they suffocate everything)- I figure that I'm doing a net good, so any folks worried about whether I'm running afoul of the law can relax- I've got it handled

Because I'm working around a lot of saplings and native stuff I wish to be real selective, something that's a bit hard to do with power tools/trimmers. Believe it or not I'm currently using some small, short-handled loppers (Fiskars): also have been using some hand pruners (diving into woodsy areas to battle blackberries and not for path creation). Right now It's the stuff that's laying on the ground that I am concerned with (for this path). Just wondering if there's something other than a chainsaw that can be used to cut chunks out in which to create a pathway* (sounds like not). My boot of preference: Muck Boot "Wetlands."
* Path is for maintenance, for getting through areas to maintain my future trees [saplings]. Native trees vs invasive species- I think I'm OK with that. Besides, absolutely no one else (other than myself or my dog is going to use these paths), it's not somewhere where anyone is going to "discover" them.
