Keep them both. You can get a pocket chain saw that takes up less space than a normal hand saw. Like this. The pouch hooks to straps so wouldn’t take up space in your bag.

Get one of those wire saw they are small and faster than a knife for getting tinder for small fires or wood for shelter. I also consider this for my own survival kit whenever I get a chance to built it.

I like this idea for desert riding. I never ride in anyplace that doesn't have trees...lots and lots of trees, so for my money I carry a pocket chain.
Not only will it cut a branch big enough to do this in under 10 seconds, but it will cut a 12" log 1 to 2 minutes depending on what kind of shape you're in, I've cut stuff 18" with it, it's helpful to have a friend at that level.
If you ride in the trees, you should have this with you anyway. I usually carry this and a hatchet at a minimum anyway.
I've used a hand chainsaw and cut through a log in minutes. https://www.amazon.com/dp/B00GMR0MZS/ref=cm_sw_r_apan_glt_fabc_Y1Y6PASNTS8GM7WXK9JB
I've never tried one myself, but this is on my shopping list. Not sure if 4.8 ounces is about what you're looking for.
