Review on Effortlessly Remove Nails With The Crescent NP11 Nail Puller Pliers In Red And Black by George Bridgewater

I was concerned this was a gimmick product but it WORKS! I tried this on large 16 nails and pushing back to remove the nail closes the clamp even tighter so they stay in well. I would still rather use a large crowbar for large nails. However, for any nails smaller it is perfect! I had a lot of old wood that had some partially rusted nails and the heads broke off on all of them with my flat bar. I tried these nail pullers and got all the nails out. That extra pressure on the teeth works great.Excellent tool I keep with my crowbar and flatbar now.
