4 Pronged Debris Grabber

two grabbers I purchased from Pryor Tools

I'll review the pole claw grabber (my order 1696) and the 4-pronged debris grabber (my order 1854): I am using these tools while digging small diameter post holes for schedule 80 steel posts. The work is being done in Montana glacial moraine, full of rocks. Each hole is 42 inches deep and 7-9 inches diameter. The claw grabber is only good for small boulders (must have ridges to not slip out of claw). The 4-pronged tool is good for many typical cobbles too deep to reach with my hand. I vacuum out gravel and dirt. Your grabbers are the only products on the internet that come close to what I need. Thanks.
