this is such a contentious subject...

If I may make a few comments... lol I will anyways.

don't try to make a knife a multi tool.

a knife on its own is the single most important thing you can bring into the woods etc., except the clothes on your back.

I have to go with a swedish bush craft knife.

durable, can be field sharpened, and functional.

also get a reasonable axe and sharpen it. You don't need to spend hundreds on this either.

a decent saw too but not too big.

I made my saw, got a good quality lopper saw blade and married it to a wooden handle. It works great and was reasonable cost and kicks the ass of any camp saw.

you can probably do all three above for your $100 if you shop around online.
