When I’m hiking, I’m usually day hiking, and it’s usually with the aim to complete a trail up to fifteen miles long and with 3,000 feet of elevation.
Weight is very important! I like to wear light runners’ shorts, an athletic shirt, and as I’m the pack mule of the family, I carry water bottles in a pack.
I could never do a folder in my pocket or a fixed blade on my belt on a serious hike. It would add weight to my legs and hips, throw off my stride, rub to no end, and end up feeling like ten pounds by the end of the day.
Maybe I could go with a light folder in the pack (BM Bugout would be great for this) but one of the only items I could imagine using it for would be to cut my own hand off should an unfortunate accident occur, and I have better alternatives.
I.E. four cellphones in the group, and a satellite beacon in pack for no-service situations.
