I was surprised how expensive these very simple tools were, but they are top quality. They are very helpful in pulling up pavers. They are also useful in scraping dirt off pavers, and scraping between pavers. My pavers were very tightly packed together and quite a challenge to remove, especially the first one.
I have a neighbor's tree that has sent roots under my pavers, lifting a few up at odd intervals. Because the pavers were slightly lifted already, it was easier to use these tools to finish removing the stones to cut and remove the roots. I think the width and teeth of the tool work well, better than a large screwdriver. Both ends of the tool are "working" ends, so you should wear gloves.
I was going to make my own tool to raise and level some pavers that had sunk down due to a mole tunnel. That was before I learned that this tool existed. It worked as designed, but you have to be patient and use the recommended technique. The tool saved me a lot of time, so for me, it was worth the money.
Was able to pull out the blocks that i needed replaced without doing damage to surrounding blocks. Pretty happy with these.
Wasn't quite sure what to expect, but after you start working on the cracks with these tools, the polymeric sand comes out and you can wiggle out an embedded landscape stone. Fully recommend!
