Swiss Army Knives are great, but it always seems like the one tool you need doesn't happen to be on the one you're carrying. Not so with this one. The Giant Swiss Army Knife ($1,000) is not the most portable knife around — it weighs nearly three pounds — but it contains all 85 tools currently available in the Swiss Army catalog, meaning you'll probably be able to find the tool you're looking for.
You can't be a man and not appreciate the usefulness of Leatherman's products. Unfortunately, some of them have grown so big that they can no longer be carried daily in a pocket. That's why we're eyeing the Leatherman k502x ($70). It's a sleek lockback folding knife that incorporates some essential tools, namely a bit driver (with six screw bit tips), can opener, and a carabiner clip that doubles as a bottle opener. Like Leatherman says: the k502x provides maximum usefulness with minimum bulk.
This handy Carabiner Tool ($60) is great to have clipped to your backpack whether you're hustling around an urban jungle or a real one. It offers a Kershaw stainless steel knife blade with "Shaving sharp" edge, flat and philips-head screwdrivers, a bottle opener, and a quick-access carabiner body made of black anodized aircraft aluminum.
