My husband found this out behind his grandfathers house many years ago. I cannot find anything telling me what it might be. Does anyone have any ideas?

I thought someone would have chipped in by now .... I'm so curious too!
Looks like a Jack hammer bit
It's an anchor for holding the tendons when prestressing concrete. It's made of aluminum to withstand the corrosion.
Not an expert so I really don't know the details how it works. Frank Holister Co. "16" probably stands for its 16 claws.
Can you show me where you found that info? Please?

Cool find, I hope you can find out more details how it's used. Looks quite sinister! :)
Outstanding! Thank you so very much!
