The plasma knives are vaguely similar to tools currently used in radiosurgery, but rather than heating tissue directly and damaging it, they penetrate and cauterise it safely. While tools like this are great because they have the potential to save many lives in situations where proper hospital care is not an option, let’s be honest: most of us just plain want some mini lightsabers.

It has new replaceable motor with electronic feedback control, which in theory will give you consistent speed under pressure. The speed range goes from 5000 to 35,000 revolutions per minute, and it has the obligatory backward compatibility with all your existing Dremel tips. [Dremel via ]

We’d not only use this to avoid putting our fingers in dangerous places, but dirty ones too. Dropping a ring in a toilet while the toilet is occupied is horrible, but now it can be one level less so. [Wireless Catalog via Nerd Approved]

Konstantin Leonenko made these from little more than a watch battery, a tiny motor, a switch, moulded plastic and the smallest drill bit we’ve ever seen. Konstantin says that he came up with the idea one day while on a trip to Berlin, and already knew he wanted to make it using a laser cutter. The original prototype was made using sandwiched pieces of acrylic, but later models moved to a skeletal, one piece design. Leonenko likes it because it pays tribute to one of the most widely used tools.

Know why we love it? Because it’s SMALL.

The device attaches to each side of the ladder and helps improve traction and level control with feet that are fully adjustable. I’m surprised something like this doesn’t already exist—but I wouldn’t be surprised if that changed sometime in the near future. [Tuvie]

I’m thinking of 15 things, in fact, all of which are listed over at oobject in a handy little list.

There’s the “minty mp3 player,” for example, perfect for the subway. Or perhaps the iPod nano dock is more your style? No? You’d prefer an Altoids tin mouse? You’re in luck! Someone made one of those too. There are even two—yes two!—Atoids tin cameras to create as you sit back and digest all the wonderful content we’ve seen stream across the homepage this week.

Lastly, there’s also an Altoids UMD case, which is the perfect addition to any GameStop storeroom. Those worthless, unsold UMD movies won’t stack themselves, you know! [oobject]

Screwdriver keys have apparently been out of production for the last decade, but now for a mere $US4.50, the two-piece blackened steel recreation can be yours one again. I know most of you don’t really care about that historial factoid. But there’s one dude out there right now sporting a keychain duct-taped to a 30-piece Craftsman set. And he is weeping — weeping, I say — with joy. [Screw Key via The Awesomer via BBG]

And scene.

Anyway, these brightly-coloured tools float and accomplish several boat-related tasks—perfect for Summermodo adventures you might have planned!

Knock them overboard and they’re easily seen and retrieved. Pretty straightforward. The handles help the tools float because they’re made of comforting foam. Bonus: The rust-resistant metal is tungsten-carbide, perfect for fighting off the corrosive effects of that salty sea air. Yar. [Amazon via Boing Boing]
