Folders carry around easier. Pocket. Fixed blades you gotta have a scabbard,usually on your belt and people look at you and go "Oh My God "! A knife, Ahhhhhhh...... I'm talking urban here. (I hate urban !)..( They are even worse about guns).
Fixed blade,you don't have to worry about a weak lockup and it folding up on you,cutting you up or worse, putting a big nick in the back of a bow your scraping.. Or, they are so long, that if the did fold, they would still be too long to fit in a pocket. (My big fish knives come to mind). Knives are like guns. You don't hunt elk with the same gun you hunt squirrels with that you hunt turkeys with etc... thing is, they are relatively cheap and easier to keep than dogs or women. I admit to having a particular love for edged things, but not too bad,I have wittled ( Har..Har..! ) the # of knives I own down to only a couple of hundred. Kitchen (I cook) fish,game,wood carving,pocket utility, etc...etc...extra's for when I lose one. Anyway The whole deal is they are tools and you need a bunch of them . My wife ask me why I need so many knives, or guns, or bows, or arrows. I ask her why she needs so many clothes and shoes. She says it ain't the same but ...? ! Really. Yeah ! "THEY" always are right.
Right ?....Yeah, They are. Plus it just feels good to go buy a nice, useful knife of good quality.
They are great trade Items and make good gifts for friends that have everything. 'specially if you make it yourself . ' Frank
