Silky makes the best pruning saws, in my experience, and in many sizes. I've had a 14.2" curved blade Silky BIGBOY 2000 and a 9.5" curved blade ULTRA ACCEL for eight years and love both. I use the BIGBOY for larger stuff on my 11 acres, and usually take the ACCEL on canoe trips along with a short parang machete. Never an axe.
Silky's most powerful saw is the KATANABOY 650, which has a 25.6" blade. I think that's too long and heavy for my typical canoe trips, but here's a video of @HOOP (Glen Hooper) successfully using and praising the KATANABOY and BIGBOY for clearing big blowdowns on Canadian boreal forest portage trails.
