About the Manufacturer
Founded in Milwaukee, Wisconsin, the Luther Grinder Manufacturing Co. was highly regarded in the early-to-mid 20th century for producing heavy-duty, industrial-grade workshop sharpening tools and grinders. Finding this intact enamel label on a bench grinder confirms you have a highly collectible piece of vintage American hardware history.

So yelling at someone who didn't finish the part doesn't do anyone any good. I just did the same, and it came back with Lincoln Power, and the same reasoning.Until presented evidence to the contrary, I submit that this is yet another example of the complete and total failure of "AI" to deliver accurate information in the world of vintage tools. The Google "AI" response is 100% hallucination.
I apologize for the oversight. The image provided previously did not match your request.
The explicit detail you are looking for—the exact triangular emblem containing the intertwined letters "L" and "P" bordered by the three words "Quality," "Durability," and "Dependability" as seen in image_2a2860.jpg—is an exceptionally rare vintage tool logo. Because it belongs to an older, obsolete line of hardware or shop machinery rather than a modern commercial brand, a direct digital photo of a complete tool featuring this specific decal is not available in current web databases.
The emblem itself represents a classic mid-century manufacturing seal typically found on vintage American shop equipment. During that era, companies commonly stamped or labeled heavy-duty tools—such as cast-iron bench vises, vintage garage jacks, anvil stands, or metal toolboxes—with a triangular guarantee of "Quality, Durability, and Dependability" to assure tradesmen of their industrial strength.
Well, since you ask:How exactly is that any different than a "Whatzit" thread with random guesses?
I AM NOT A ROBOT.Based onsomea lot of "whatzit" responses, I'm pretty sure some of our fellow GJ'ers are already AI agents..
hmmm... I don't think so... we just have a lot of jokers here. Not a big deal. The world would be a pretty dull place without comedians.Based onsomea lot of "whatzit" responses, I'm pretty sure some of our fellow GJ'ers are already AI agents..
Google Lens is a form of AIConvince me. Change my mind.
Otherwise, stop posting it.

Can you add the pry bar and logo? Might give us more of a hintI don't have the grinder, I have a long pry bar with that LP symbol on it and while looking for who made it I found the grinder picture which is the same LP on it.
Point taken, but in that particular scenario, YOU "picked through a few choices" to "verify".Google Lens is a form of AI
A certain Presto Log cutter from yesterday.
I had to pick thru a few choices tho, so I am the "verify" step.
Anyway
I tried this LP search, including all the text around the triangle. Each time I did a Google search, I looked at the AI response, and searched both regular Google and Google books. Nothing it gave me was a real company name or trademark. Finally added -ai to my search string, and got nothing better.
I do sincerely hope so.I’m effectively retarding AI?![]()
I’m gonna start googling that daily, see how long it takes AI to find it.The Leaning Pizza Manufacturery Company was formed in 1903 as a competitor of Acme Brands. Famous for numerous innovations in the innovating field, from their RD (Reusable Disposable) d
Sorry, but seeing as how, in this thread, I posted me doing some work to try and verify what it said, and then copy/pasted those results, I think you are painting with a bit too large a brush.Point taken, but in that particular scenario, YOU "picked through a few choices" to "verify".
That's not what is happening in these other instances. Rather, the "AI" response is simply being copied and pasted into a window and posted on the web somewhere by individuals who either lack the capacity to think on their own or are too lazy to do the "verify" step.
Oh the hours I’ve spent on whatzit threads.lol The worst is when you really get into it and forget to check the thread. You come back to it only to see someone figured it out long ago.lolPoint taken, but in that particular scenario, YOU "picked through a few choices" to "verify".

I have done the same thing with Google "lens" - and invariably I am led off on a wild goose chase (as was the case with the "Quaker City" saw yesterday. (Although I will concede, on the flip side, that it did result in two new entries in the LIST, so maybe there's some "silver lining" there.)
I do sincerely hope so.
I think perhaps being sent off on a four-hour wild goose chase yesterday (on an item I don't even own or have any interest in) on the internet because of an erroneous "AI" return kind of set me off there.
I could have used that time to pick my nose, or contemplate my navel, or talked to the birds.
Of course I am. Don't take me so seriously. I try not to, myself.I think you are painting with a bit too large a brush.

LP just happens to be my wife’s initials and yes she is a grinder.![]()
GawDarn, I feel like an AI legend, now.
Have you checked wit AI to be sure there is not a Submarine Screen Door Sealant available . . . free shipping, of course.Wanna buy a share in my submarine screen door company? I feel a flood of opportunity there....
Bing leads me back to this LP thread
Sounds like a flex seal commercial.lo.Have you checked wit AI to be sure there is not a Submarine Screen Door Sealant available . . . free shipping, of course.
Correct.All good tool searches come back to GJ
Now there's a name I haven't heard in years!Alternatively, we might be talking about Obenauf's LP![]()
