Not sure, but maybe he means replaceable blade box-cutter type utility knives?
Yeah, the op didn't give us much to go on. Price range, tasks etc. Over all I'd say that you should look for a thin blade since they cut much better and longer since they have good geometry.
For a fixed blade it's hard to beat mora's.
For folders, pretty much any knife produced by a big name company is going to be good. I'm partial to the cold steel triad locking knives.
For folding replaceable utility blade knives, I have a husky brand that I picked up 4 or 5 years ago. It's awesome for $9.95, rock solid lock up and quality materials.
My bad. I looking at knives that are good for box cutting but can also be used cut rope, thin wire or act as a wire stripper. Something you would use in a warehouse.
