This is the difference between Leatherman and the myriad of Chinese knockoffs. The knockoffs may be very good just in and of themselves, but your Leatherman will actually have a warranty and the manufacturer will actually stand by it.
I have three Leatherman tools: A Skeletool, a Wave, and an OG Surge that I've had probably since late high school -- so old that it predates the swappable wire cutters feature. The Surge in particular has been used for damn near everything from repairing bicycles to cutting tinder, and I've never broken anything on it except the replaceable screwdriver tips.
I have a "Flissa" Chinese knockoff Wave-ish thing that I keep in my motorcycle tank bag because the risk of losing it or having it stolen is greater than the risk of breaking it in that case, and the higher end Leathermans have gotten so damn expensive lately that I really don't want to find myself having to buy another one. The Flissa is great; Tim Leatherman was right, the Chinese eventually hit that 80% quality figure and probably beyond. I should probably do a writeup about it at some point. But I know in the back of my mind that if I ever manage to bork it my only recourse will be to buy another one, and there's only so many times you can do that (about three, actually) before you've no longer broken even.
