Sure looks like it could tear up a valuable coin....how does one know for sure an item is a ring, pulltab and not a coin when covered with dirt?
Here's the other info I have gathered on this from previous posts:
"(A photo was posted on Jan. 23 by Rentasquid -see above). My good Tesoro friends, after many years I finally came up with a tool that gets rings, pulltabs, etc. out of the ground without digging a plug. Made from a Farberware 8" bread knife ($11.00 at Bed bath & Beyond).Just stick it straight down into the ground and pull toward you and up, it hooks onto damn near anything. Tried it at a local park the other morining, pulled up the junk in the photo, no rings. Everything came out real easy including the soda can half. Was able to use it just two times before the the cold weather set in. No plug to cut, so no dirt to put back, or just a small amount at times. It usually leaves just a slit or two in the grass. With good pinpointing the target can be snagged the first swipe. I wouldn't use it searching for old coins. The notches in the blade were cut one half inch wide by three eights inch deep and spaced one half inch apart, then grinded to make them pointy. A carbide hacksaw blade, Dremel tool, and a grinder was used. It's a lot faster than cutting a plug for each target. If you do make one you'll find twice as much junk in less than half the time, maybe even a ring."

"Go down to Jan 23 and read the post on The Ring Tab Puller. I made one yesterday and used it today and dug a lot of alum but i got a nice mans 14kt Ruby Ring with a Fancy W Initial. It weighed 5 Grams. Took about 1.5 hrs of hunting to pull it up. I am a jewelry hunter and this thing once you got the technique down it is really fast and works great. Got to add a bike grip with a flange on it so hand won't slip down to the blade. Anyway for you guys that are snowed in and are getting bored it is a real nice thing to make yourself and save a lot of time. Love mine. My SE has got to go back to Factory. If you lay a qt, dime and nickle down swing right to left the tone changes but the digital or the cursor stay locked on the first target QT "
That's all I know. I think Tinfoil might be the originator of the item. Rentasquid said it is not his item.
