Small chainsaws

If you were to use a chainsaw in a remote location, you'd also need to take cut proof chaps, gloves, jacket and boots.

I'd just take an axe good fitness.

An axe would be much more fun.
A handsaw is easier and more precise than an axe. You are only removing a 3mm slice of wood.
I've cut a bit of wood over the years, use a saw, take your time, put some tension on the wood to open the cut up, let the saw do the work. Rest, change arms often.
You never have to cut it through entirely the first time. Set a timer for 12 minutes. That'll do.

A chainsaw will rip through anything less than chainmail armour instantly. that is what they are designed to do.
It'll rip open a major artery before you can even gasp. Rip it open WAY beyond any repairable stage.

If you live in a rural area where trees can regularly fall across roads during a storm and no-one else is around an axe is pretty useless if you want to get home anytime soon.
