Can't find the screwdriver... HA!

This may seem like a lowbrow request, but I'm looking for a specific screwdriver to give my Dad for Christmas. I saw it advertised "Only on TV" once, and haven't seen it since. I was wondering if someone has seen the same thing and knows what it's called or where I could find one.

It's a ratcheting screwdriver. Set the ratchet one way and no matter which direction you turn the handle, the shaft rotates clockwise. Set the ratchet the other way and no matter which direction you turn the handle, the shaft rotates counter-clockwise.

Thanks in advance!

did you google it at all? here are a couple of choices

You wrote,

"Set the ratchet one way and no matter which direction you turn the handle, the shaft rotates clockwise."

From a physics standpoint, is that possible. If I apply a clockwise torque how could the screw move counterclockwise? You would need two hands for such a device to work?

^Obviously did not read the original post. Notice it's not simply a ratcheting screwdriver. (That was meant for gsal)

It's a Kobalt Double-Drive. I'll edit a link in when I find it.

Edit- Here's a description. http://toolguyd.com/2011/09/kobalt-d...r-set-preview/

Looks like Lowe's online is sold out.

No, those aren't the right kind of screwdriver, I guess I wasn't clear.

Assume the ratchet is in position A. Then turning the handle CW will turn the shaft CW, and turning the handle CCW will also turn the shaft CW.

Flip the ratchet switch to B and the shaft will always rotate CCW, whether you turn the handle CW or CCW.

So such a device would require two hands to operate?

gulfcoastfella

The handle is connected to the shaft by a set of gears.

Your comment still stands incorrect. See my edited post for the link to the tool he's asking for. (Heh, we're in some kind of editing warp, where posts soon lose their context)

That's exactly what I was describing. Thanks for finding it.

Spinnor

From the link it looks like you use two hands and must for it to work?

Edit, reading the link further, yes.

S_Happens

Yes, it requires two hands. You hold the collar with one and twist with the other.

You have both options.

"To engage the Double-Drive mechanism, you hold onto the screwdriver’s blue sleeve with one hand, and turn the handle with the other. If for some reason you cannot hold onto the blue sleeve with your other hand, the screwdriver will still operate in the same manner as a ratcheting screwdriver."

Thanks for finding it. I just bought one on eBay since Lowe's was sold out; and if Kobalt holds the patent, that would explain why I saw the commercial for the other one just once. They must have pulled it from the air.

S_Happens

I suppose if you REALLY wanted you could rig up some vice grips or a clamp to hold the collar if you wanted to only use one hand. That's just silly though. :P

S_Happens

I can't find the short commercial, but the one I've on TV is specifically this Kobalt one. There is a longer one with prices and all on the Kobalt site.

Do people really need to think about which way to unscrew and which way to screw?
Do people prefer using 2 hands than one so that they don't have to think about which way is to screw and which way to unscrew??
Did people got paid to think about such an idea and engineer that device???
Do people relly buy such thing for anything else than birthday present (or father's day)????

Einstein said 2 things have no limits...

I think you are making assumptions about how the device is meant to make driving screws easier.
For one, it's not about 'not having to think which way to screw'. One of the things it does do is make more efficient use of the motion you already have to do anyway. It does twice as much work for the same motion.

No he didn't. The internet is not your friend.
