i spend a lot of time in the bush in the rivers fly fishing. I’ve honed my kit right down, here are some ideas to start people thinking.
For knives for fishing I have used these options depending on needs - all are folders and most with locks - for bushwalking I often carry a light 3-4 inch fixed blade knife with a make shift sheath, and there are lighter options with longer blades and handles eg repurposed kitchen knife, cheap but good for food and/or camp use and a handle of 4 in fits my hand better. But for everyday fishing, a folding knife in my belt pouch is best.

Gerber flat 2.5in blade 41g
Opinel #7 3in blade 33g
Small Gerber 2in blade 24g
Razor knife 2in blade 7g
Ceramic 1in blade 2g
For overnights/remote fishing I’d take the “larger” 3in folding knife or a fixed blade as the longer handles are more effective (for food and general use, including making tarp stakes).
For day trips I’d just take a small folding knife. I don’t like using the disposable razor knives even for food, I’m always worried about cutting myself with these razors as they are hard to hold and use safely. I’ve also recently been testing the teeny tiny ceramic knife. It’s proven surprisingly effective in many cases - in most outings I only use a knife for cutting food pouches - but I found I could actually use it to cut meat and even prepare a trout for dinner one night. But my preference is still a blade about 2-3in in a folding locking format - the longer handle is easier to use.
For interest at the bottom of the photo are two fire options and a light option. All waterproof - everything in my kit has to be waterproof. The flint rod and mini steel weighs 11g. The mini bic weighs 11g and can be dunked in water, dried on my pants and used. The fire starter is a makeup pad soaked in Vaseline, 3g . With either fire option and the starter I can and have lit a fire in the rain. The coin LED light with nylon neck loop (6g) is surprisingly effective for finding my way back from the river to camp in the bush at night.
