It's good to axe questions
Does Mears use Granfors Bruks axes? Yup, he sells them too. Question is, what does he use them for?
I wouldn't go after big windfalls with that small axe. It would be good for limbing and stuff under, oh, let's say 4" diameter. Any bigger than that and you're gonna get a real workout. I would want a full size felling axe to go after trees other than saplings.
Consider a bow saw for log-sized stuff. Look at Sven saws if you want something really packable. They are a lot quieter than an axe if you are doing something you shouldn't. Had a buddy who like to swipe slash timber for his wood stove and he used a Bosch electric chain saw running on a car battery. Worked pretty good if you didn't overwork it and get it too hot.
I pack an axe in a sheath that covers the head and there's no problem concealing one in a pack.
Now, about cutting windfall trees. Be really careful. You can release stresses in fallen trees and they can roll over on you, kick out at you, and other trees can come down once you release the tension. You are playing with big dangerous jackstraws.



Saplings don't scare me, but when you get up to around 8" and larger stuff, it can get serious. Keep in mind that wet timber weighs a lot more than the kiln dried stuff in the lumber yard. I would rather climb over or around.
