Testing Out a New Screwdriver

[lynn2323]

I’ve been using a screwdriver without bit holder for sometimes. And the magnetic holding power is just too weak and the bits keep falling out. Therefore, I started looking for a new screwdriver with bit holder and came across this screwdriver on Amazon. The bit holder on it is just like any other screwdrivers. But is said it has some kind of elastic mechanism to relief wrist pain and add some elastic torque just like rubber band does. At first, I was really skeptical about it because it sounds gimmicky. But I thought why not give it a try and test it out.

The handle and the shank of the screwdriver is connected with elastic material, so it does let your wrist adjust in a certain angle. Since I don’t have wrist pain, I can’t say anything about wrist pain relief. However, it lets me do my job easily when I’m in an awkward position.

And about the elastic torque assist. As I’m testing it out, I found the elastic material stretches under torque pressure, and builds up energy like rubber bands do. Therefore, I find it easier to loosen tight screws with it. As when tightening screws, it only makes a difference if the surface is somewhat hard, like wood for example.

What I’m concerned about is the elastic fatigue. Because the elastic material is constantly stretching under pressure, it may fatigue in a matter of time, which I’m not encountering it yet.

Still a cool tool tho. And hope you guys enjoy the review and share some of your thoughts.

It looks like polyurethane which should take a LONG time to wear out.

Glad to hear that, thanks for the info!

I don't understand how the 'elastic torque assist' can be helpful but I haven't tried one. Interesting screwdriver though. Thanks for the write up.

From what I've experienced, it builds up energy as you're rotating, then returns the energy back onto the screw. Which makes loosening tight screws easier.

I think its just the larger diameter of the grip, more torque.

That prbly helps too! The shape of the handle is pretty unique, and it's pretty ergonomic surprisingly. But I actually would like the handle to be a little bit bigger.

looks interesting

Can you tighten the bit on? Is the bit holder a chuck?

 

[bonneyman]

Perhaps it works like those Makita Gold impact bits that "flex" in their mid-section while under load and then gradually apply the force to the fastener, thus avoiding strip out?

Anyway looks pretty cool.

Gotta link, OP?

The bit does lock in place with the quick release bit holder. Not the kind of holder you see on power drills tho.

I've never tried the Makita bits so I can't say more about them.
But after a quick search, maybe they do have somewhat similar concept.

Hmmmm interesting design. I found a guy on youtube reviewing it, but it's sponsored tho. Hope it's not too biased.

The whole time i'm thinking, just chuck the bit in that drill....

Thanks for sharing the video! I guess the screwdriver will come in handy if you want to drill a hole but you don't have a drill? lol

Anyway, this video does show that the handle flexes to adjust angle.

LOL
I think he's trying to show that the screwdriver is easy to apply torque with it's "elastic torque assist", which I'll admit is quite impressive.
At the end of the day, it's a sponsored review.

You know what else easily applies torque? My M12 impacts/drills/drivers.

Just kidding. Sort of...

Seriously though, If I need that much torque, I'm going with a machine to save my wrists. Also, it looks like the diameter of that screwdriver handle is larger than my M12 drivers' heads.

It isn't going to apply more torque than you could with your hand but I'll bet the spring makes a satisfying snap when it finally does break a screw free.

Damn! Amazing ..NOT! Remember the 70's Lawn Mowers with the flip over handle, crank a dozen times, and slam it home, cranks the motor? Well one good yank ya rope start, way faster! SAME DAMN EFFORT DONE! PT Barnum was right.............( get a small LI batt hand drill)..
