Interesting & creative tools, even if they are flops

-
That's exactly what happened with me yesterday. I only could find 12" spares at the garage and was tinkering with the saw to see if it extended to for otehr blade lengths. Low and behold, spare blades! :)

How many of you have worked with guys who didn't know there were spare blades stored in utility knife?
 

My grandfather had one of these, the Yankee Screwdriver. The idea is that you push on the handle and as it travels down the shaft it spins the bit and either screws in or screws out whatever fastener you are working with.

Reality, you wind up punching whatever material you are trying to screw the fastener into….

My Dad had a couple of these. Neat concept but heavy and awkward. Battery powered handheld tools made them irrelevant.

Elwood Blues carried one. Fast forward to 2:25.

Only Hollywood could successfully pull off the use of that tool!

For the love of God don’t try to use it, you’ll be bleeding all over the place!
 
I'm trying to thing of something that needs lots of leverage and there's not much room for deep jaws.

I have some milsurp wire cutters and they are pretty big and hefty.
Oh. Like pex pliers are
 
Ugh! Dropped it again. &%$!!

Problem solved with one of these?

Ullman is still selling similar screw starters so maybe they are handy for some situations.

One more variation for now. I'm pretty sure I have more somewhere.

I came onto similar screw starters back when I was turning wrenches and cars had points and condensers. Good luck with those without some way to hold the screw and start it.

I've still got both flat and phillips head versions made like the Ullman in the photo.
 
Curiosities that are obvious what they do, so don't go in the "What's this tool?" thread.
Whether they were successful may be another matter - but someone(s) thought they were worth making. :)

No name, Made in USA, Nut driver with built in storage on the shank. LOL Handy or annoying ?

Does it work?
I have no idea.
I have one. Somewhere. It came in Sears largest tool set around 1970. Useful? Very little. Used it a few times over the years just not real handy as jaws are spring loaded so ot doesn't stay tight. Regular nut driver better. So is Speed Handle, which I have always used a lot.
 
Funny have a couple of speed handles
Haven't used one in years
Liked them on oil pans
Think I'm going to make my kid use it tomorrow..
 
Ugh! Dropped it again. &%$!!

Screw starters the best tool to install distributor plate screws, replacing points & some condensers. I'd Bet Lisle still make them.

Found partials of two more, but this one seems to be complete.
Got piece of that somewhere

I have several that were my grandfather's, who was an army mechanic(not sure which war).
One is maybe 8" long, the rest 10 to 12" like that one. Also having repaired Wood Boats they come in handy occasionally. Like using a speed handle but you have to keep in line w/screw & keep downward pressure on up stroke.
What gets me is before screw guns this was the fastest way to build boats. You've got to drill Exactly the right size hole with drill that sizes for thread and shank that's unthreaded is a different size so you need a taper drill bit or step drill. & countersinks mount on the drill bit for flathead screws. And they used only slotted screws then so it was even harder. And you have to lubricate the screws or you'll either twist them off or can't bottom them tight.
 
Predrilling still makes the strongest connection. Slotted has the advantage of applying full torque across the head and is the easiesto chip paint out of the slot. Definately requires a lot more skill than powering in one of the anti-camming torx type drive heads.

Boat builders went to Reed & Prince screws(Frearson) & also square drive(Robertson), and changed from Brass to Silicon Bronze(stronger). Some have used Stainless, but black rings appear around heads and can be seen under varnish, like some house decking screws do. Most SS screws use slotted heads for boats, as of 12 yr ago.
