I narrowed it down to their Style PS and Squirt PS4 (didn't really look at other brands), which are very similar. Squirt is a bit bigger (odd because the word "squirt" can be used to mean small), but both have pliers and scissors.
- Smaller and lighter
- Has a built-in carabiner clip
- Has tweezers!
- Has a nail file, which people say is more suited for nails than the Squirt's wood/metal file
- No knife
- Fewer screwdrivers
- Has plastic parts, compared to aluminium on the Squirt
- Has a knife
- Aluminium on the handles, instead of plastic
- Knife doesn't lock
A word on Leatherman's small models: they group the Squirt, Style and Micra (6 models total) together - the instruction sheet is common for all 6 models. Briefly, the Micra is an old model which (whose?) main tool is scissors and has all-steel construction. Style tools all have holes in their handles, like the Skeletool. The Style is the simplest tool with only one handle like Swiss army knives, not the double handles. Style also has PS and CS; the PS has pliers as the main tool and scissors, while the CS has scissors and knife. Squirt has ES4 and PS4, both with pliers as the main tool. The only difference is ES4 has wire-strippers on the pliers.
The black part of the tool is glass fibre reinforced plastic, which fortunately is only used on the part of the tool you see here (I don't think plastic is very durable). You can see the tweezers sticking out from the black plastic.
After buying this, I found out Gerber has a similar product: the Dime. It costs less and has a few more tools - including a blade and package opener. However, it:
- Is made in China (not really a problem, but in this case its build quality is lacking)
- Handles gouge each other when opening
- Pliers spring tends to buckle (http://forum.multitool.org/index.php?topic=36210.0)
