I had an early Leatherman without locking blades, including the screwdrivers. Avoid nonlocking screwdrivers at all costs! I have scars on my knuckles to attest to the fact. . . .
I moved to a Gerber with locking blades and have had it for years. I wear it on my belt and use it somehow every single
day, often several times a day.
Nowadays all the good multitools have locking blades, I think.
So as said above, just shop for the size and features you want. You'll be very happy.
Oddly one feature I wanted was a corkscrew, which doesn't appear in many multitools. But it's one of those things that when you need it, you need it. . . .
