If you have issues with fine cuts (like fishing line or tissue paper) the scissors on a victorinox swiss army knife work very well. Get a 91mm size knife for scissors that aren't laughably tiny, but only smallish.
On the opposite side, tough items, like leather or pennies (!) can be cut with EMT shears.
Victorinox built in scissors are great. I use mine on a Classic all the time. They will send you a few replacement springs for free if you ask. It's the only problem I have ever had and that's after years and years of abuse.
