I always feel that food and water are priorities. I carry well over 100oz each time I hunt the whole day, just about 90oz for a half day. I hike a lot so it is necessary. Protien bars, nuts, fruit(dried ok), maybe a candy bar for fun.
My Wyoming saw is my heaviest piece of gear but I can fall a pretty big tree if needed and make really quick work of an elk with it. I have multiple knives so I understand the redundancy, sharpners diamond stick and carbide style weigh nothing. Rope (25') because cord is too difficult on the fingers, especially when cold.
I actually have an extra coat in my pack in addition to the one I start the day in, have made a shelter with it, sat on it, worn it for rain gear, great pillow...Toilet paper, baby wipes(absolutley essential for many reasons). Head lamp(LED) with extra batteries ( really tiny, not C,D-cell), compass, altimeter, electrical tape, orange tape, montana decoy and legs, current book (optional)...
That is just the stuff that is alwys with me, I carry my binoculars, assorted calls, bino pen, whisper dust,and a few more things on my person. I say, consider yourself good on light weight and don't remove much more but maybe upgrade a few things that could drop oz to lbs. I won't even weigh my pack due to fear.
