Size
The tool is a medium size; significantly smaller than most common full sized multi-tools, but a lot bigger than the standard keychain fare. For me it’s on the large side of “pocketable”.

Thickness compared to a Juice S2:
Plain Blade
To me it’s a very nice length- just a hair over 2.5 inches (6.5 cm). That, along with its slip-joint design, keeps in legal in most places, but still long enough to be very useful. Its edge holding is nothing special, but it sharpens up quite easily.
Plain Edge:
Serrated Blade
Same length as the plain blade, but the point comes down in a sheepsfoot pattern. The plain edge at the tip helps make up for lack of scissors if you keep it sharp. The serrations are designed well and cut effectively.
Serrated Edge:
File
On both sides the cutting surface starts close to the handle and extends to the tip, giving the most usable edge possible. I’ve used the standard side on both wood and metal, and it’s worked great on both. On the other side, the diamond file is something special- very fine and yet quite aggressive. Lastly, there’s a “metal saw” on the edge, but to be honest it’s not all that functional.

Awl
The awl on the KF4 isn’t very sharp, but it is a handy feature, and works great for putting clean holes in drywall/plaster, and general poking around.

Saw
It’s thin, it cuts well, and is amazingly long for the tool’s size. The saw is placed in the same slot as the awl, which needs to be opened to get to the saw.

Ruler
The KF4 was the only Juice to have a ruler printed on it’s scales:
Pliers
Though they are not as strong as a full sized Leatherman, they open wide. And more importantly, they feel nothing like a keychain. The wire cutters are small but functional, and the hard wire notch works well.

Phillips
Nicely cut, fits both #1 and #2 Phillips heads equally. I can use this as fast as a “real” screwdriver when it’s stretched out.
“Stretched”:
Squared edges:
Flat Drivers
There are medium, small, and eyeglass sizes. All are chisel ground, but have worked well for screws and light prying.

Eyeglass:
Lanyard Ring
It’s small, and hides away in a cutout in the Phillips without wasting any extra space. It does require some tool, like a key, to open it.
