Apart from personal preference, do the multi-tools emanating from brands such as Leatherman, Gerber, Victorinox and so on have worlds of difference between them when compared apples-to-apples ? I would think that the steels used need to meet certain strength requirements, leaving special finishes/coatings, price, probably looks, and whatever special elite military based teams who use it as the deciding factors for selection. Or is there much more to it?
