Screwdriver identification.

Picked this up and have no idea what it is used for. Any info would be appreciated.

It's a screw holding screwdriver

You slide the ferule down the shank to align the blade, insert in your screw, then slide the ferule back up and the blade misalignment will hold the screw.

Here are a couple of Craftsman screw holding screwdrivers. They can hold a slotted screw by putting the tips in the slot of the screw then pushing forward on the sleeve thereby exerting pressure on the outside of the slot. In some instances it really helps if the screw needs to go down a hole to start.

That's the oldest one I have seen

Here's an early one reminiscent of the Upson HOLD-EZEE concept. Never could find any info on it. Link here.

"Ebonite" was a trade name for vulcanized hard rubber, used for various things like fountain pens and bowling balls in the days before more modern "plastics" became available. I'd date that to the first quarter of the twentieth century, maybe the first third.

If the screwdriver were intended for electrical applications (which isn't impossible at all) then Ebonite might have been used later than that for its dielectric properties.

Not if but since. (I think you missed the SHOK-PRUF branding...)

Here are a couple of Quick Wedge drivers I found at a Nevada garage sale in September.

That patent was issued 1929

Thanks for the great info everyone!

Your thread got me started so I looked through my toolbox last night. My preferred screw starters are in the second picture although I’ve used both on many occasions.

Holding screwdrivers are something you don't use everyday but when you need them they are lifesavers, especially in tight conditions of places where you can't afford to drop a fastener. They are really useful for getting slotted screws started but were never intended to be used to torque down a screw. If you try to tighten a fastener down with a holding screw driver, you will bend and mess up the blade tips. Use the holding driver to get the screw or machine screw started (and make sure you are not cross-threaded), then go to town with a regular screw driver to finish the install.

I've got a small collection of screw starter drivers but nothing has a tip on it like the OP's. Cool!

 

[Oldtuleguy]

I don't know, that may be the oldest one

 

[d42jeep]

It’s certainly older than any of mine.

Thanks again for all the great info. I found it at a estate sale in a pile of other screwdrivers. Paid .50 cents for it!

Nice
