First multitool / knife

If all you are looking for is a small blade for food prep and some scissors for first aid applications then the Victorinox Classic is your best bet. The tweezers can also be handy if you ever hike through prickly stuff.

Anything from Spyderco is excellent. But personally I prefer having scissors, much more practical for most everything you will need on trail. Except in winter conditions I almost never bring more than my Swiss Army Knife for basic trail backpacking.

I am a guy who LOVES my big blades, saws, and axes for woodcraft and winter bushcraft, but for standard on trail excursions you will never need more than a Victorinox Classic. Don't waste money on a fancy locking folder or fixed blade if you don't have a planned use for it.

I agree 100% with Andrew. Inexpensive too. Win, win.

Leatherman Style

the Leatherman Micra is an excellent pair of scissors with a spring, plus tweezers, a blade, screwdrivers for glasses and headlamps, and a handy file.

I dig!

A Leatherman Juice S2 would also be good if you wanted fully functional pliers. 4.4 ounces I think.

It's only 24 gram, but has the following:
0) Spring-action Scissors
1) Knife
2) Flat/Phillips Screwdriver
3) Nail File
4) Tweezers

For $17 delivered it's a best UL multitool.
