We’ve seen a variety of multitools, but this Credit Card survival tool will actually take up the least space. In fact, you can keep it in your wallet, because as the name implies, it is the size of a credit card. Perfect for DIYers or anyone who wants to be prepared, but doesn’t want to carry a Leatherman multi-tool around.

The Credit Card Survival tool packs a can opener, knife, screwdriver, ruler, wrench, saw, and more into a credit card-sized package. It’s so small, you’ll always have it with you, because chances are you’ve always got your wallet on hand.

We’ve seen our share of multi-tools, but I don’t think we’ve ever seen a multi tool pen before. My guess is that this would be MacGuyver’s pen of choice. It’s got so many useful tools inside, it will definitely get you out of a jam and help you build a plane out of duct tape and porn mags.

Tools include a Ballpoint Pen, Hole Puncher, Stainless Steel File, Short Cutting Blade, Flat Screwdriver, Wire Sleeve Remover/Small Nail Remover, Ear Pick(wtf), Long Cutting Blade, Tweezer, Philips Screwdriver, Stainless Steel Fork and Saw. It’s worth a shot at only $14.95. You never know when you’re going to need a pen AND a fork at the same time. And there’s always the rare occasion when you need both and an ear pick.

Seems like the new generation of multi-tools have some odd designs. Much like the Spyderco Byrdwrench, the Lil’ Guppie (doesn’t that sound like what the skipper would call Gilligan in an underwater Gilligan’s Island show?) has an odd look.

The Lil’ Guppie is tiny enough to fit on your keychain, but super versatile still. The adjustable wrench can open up pretty wide for it’s size, and it’s tininess is actually an asset, letting you get into all kinds of tight areas. It also sports a razor-sharp blade inside, and it’s tail is a flat-blade screwdriver bit. Need a Phillips head? It conveniently slips right out from inside. Of course it wouldn’t be a multi-tool without a bottle opener, so it performs that duty as well.

The Spyderco Byrdwrench has an odd name. It’s not a wrench made by spiders for birds who spell their name with a Y like the British rock band. That would just be silly. What it is, is a multi-tool that’s a bit different from some other multi-tools. It sports a combination of one-hand open knife, slip-joint pliers, bit driver, and an adjustable crescent wrench.

It’s also got a rough punch file/hole-starter and a steel belt clip, and can be separated into two halves to reveal the four screwdriver bits inside. While I’m sure it’s convenient and it does have an interesting sort of industrial look, I’m not really sold on the idea that it’s somehow better then my trusty Leatherman multi-tool. The price is about the same at $77. If anyone has one, let me know how you like it.
