those are two totally different knives. it shouldnt be too hard to choose between them
the zt is huge and way too heavy for carrying every day...its really more of a folding prybar than a practical blade
the chinese folder by lum is pretty hard to find and therefore overpriced, so its also probably not a good choice. but its a nice medium sized gents folder suited for edc if thats ideal
my advice would be...dont spend 80+ bucks on one of your first knives...experiment with different brands, blade lengths, blade shapes, flippers/holes/studs, handle materials, assisted opening, everything. its very unlikely that you know what you really want now, so lurk the boards, read reviews and watch videos on youtube. just dont spend too much on your first few knives
