+1 on the Stanley "Shark" saw......been using them for years. It looks like the Sharp tooth is probably the same model now. Relatively cheap and you can pick one up tomorrow if needed from pretty much any hardware store.
I have used one of these for decades = Sven folding saw. Light, sharp, 21 inch is the one to go with. Compact, packable. Good on bone, good on small wood (camp stove wood and poles). Only recently needed a new blade due to wear and dulling. Good idea to keep a spare so you will have it when needed. Have used on wood, elk, deer, antelope, bison, but not moose.
