It does have all the usual characteristics. I have a No. 2, but it's marked differently.Is this a Pexto? Only marking is a "2"
Nice find. I've got one just like it!I went back to the sale and grabbed this one, no markings.



What does that have to do with anything?No idea what I'll do with it
Is there room for it in your Yankee drawer?
Drive some screws with it without disengaging the tip from the screw or releasing your grip on the driver.Works perfectly. No idea what I'll do with it.

That is a cool find!This is the first one I’ve ever seen like this. The ends are interchangeable from a slot screwdriver to the three different robertson screwdriver sizes.

I guess I’ll make some changes then.^ Not under his name. I checked.

Yes. fixed it for now, but.... where is the patent?(You saw that you don't have this company name or address in your list, right?)
Hey, I’m the rookie here… I didn’t realize that I’m supposed to know how to do everything. Heck, I was lucky enough to stumble onto and acquire this tool… but I’m still learning.Yes. fixed it for now, but.... where is the patent?
I'm going to shoot this in to Jeff - odds are Robertson also applied for (or was granted) a Canadian patent as well (if that "1930" date refers to a U.S. patent.)
Really curious as to exactly what they are calling it on the patent document.
for now:

You're fine.Hey, I’m the rookie here… I didn’t realize that I’m supposed to know how to do everything. Heck, I was lucky enough to stumble onto and acquire this tool… but I’m still learning.
I was addressing @four.cycle. Nothing for you to do except relish your find!I guess I’ll make some changes then.



Might try posting it here.I picked up this wood handled 10 1/2" slotted screwdriver with holding sleeve (only marking is a “PAT PENDING
Nice one! And you're in good company here, Nitro. There are a few other screwdrivers on this thread as well as on the Winchester thread, along with other types of tools, and several admirers, including mine, although I have recently sold my collection.I am a long time fan of Winchesters other products. I thought this was cool.
Nice WORTH* (PEXTO). I have a few Prince & Prince, but they are not too common in the wild in my experience. Does it have all the use cases marked around the handle on the flats? I'd like to see entire tool photos of the Hibbard's True Value and the (B)M(Co)(Braunsdorf Mueller).Found some cool ones in the mix
