What is your perfect 4 inch blade to take with you on your outings backpacking hunting camping etc... and why.
I find slightly different needs for hunting, car camping and backpacking.
For backpacking, weight and repairability are key. I carry an Opinel and Leatherman Squirt.
For ski touring or other trips where my Emberlit wood stove replaces my Trangia or Svea stoves, I trade the Opinel for a Mora Companion HD.
For hunting, I prefer a hollow ground blade so the Opinel gets swapped for a Buck 110. It's an old one with 440C.
For car camping, the Opinel handles food prep and I add a hatchet for splitting wood.
If I had to pick just one, I would take the mora companion HD.
You might look at a Viruovice's YouTube channel. He's a hunter from Japan and his videos test many knives side by each. He's not posting so much right now but the collection of videos is stunning.
His favorite for both hunting and bushcraft is the BarkRiver Bravo II. But, in one video and compares his Bravo II to a Mora and concludes the Mora is almost as nice for 1/10th of the cost. I like the Companion with the blade convexed a bit.
I would rather cut meat with my Mora than process wood with a hollow ground blade.
