Speed Handle Screwdriver?

[lptools]

Hello, Does anyone know the correct name for this screwdriver, and its use? Wood handle, brass ferrule, 5-3/4" overall length. Round shank, flat tip, appears to be well made. Regards, Lou

Lou, I always called mine the speed handle screwdriver.   no sore palms using it with lots of screw to put in.

Klien tools calls there's the " crank handle screwdriver"

How can you keep the blade in the slot as you crank it?
I like slotted screws on general principles, but...

What does it say on the handle?

Always heard them called the electricians screwdriver,  great for putting in switches and switch plates.

The Klein version, at least, is intended only for machine screws, which are under low stress as they're driven.  I'm not sure why this design is superior to a Yankee type driver, but Klein continues to offer them, so sparkies must like them.

Hello, Thanks  for the info. There are no markings on the shank, or handle. I agree this is for light duty, maybe some sort of assembly. Use the crank until snug, and a regular screwdriver for final torque? Thanks again, Lou

With that shape, you could use the tool for final snugging, too, treating it as a T-handle driver.

Yep.  That is what the hairpin curve is for.  Apply a little thumb action.

Hello, thanks for all of the info. Another thanks for asking if it is marked. I took another look,, caught it in the right light, and here it is. ADBRO Mfg. Co. There is another line, that I haven't figured out yet. 3rd line reads Patented. The patent number is 872, 048. Amazing that the lettering survived, looks slightly raised in ink, then the finish was applied over the lettering. Thanks kwoswalt99 for nudging me to look at the handle, Lou

Hello, I have attached a photo of the handle. Thanks again, Lou
