HighFree 10 Packs of Wedge and Feather Shims 5/8 Inch, Concrete Marble Granite Rock Stone Splitting Hand Tools

Worked very well

These worked really well for breaking up large pieces of concrete. The rubber rings are convenient for holding the pieces together. Those started to break with repeated use. Thankfully you don't need the rubber rings to use the wedges, you can just set the 3 pieces into the hole and collect them when you are done. The rubber rings are really more of a convenience since they hold the pieces together making it easier to reset. If the seller provides an option to purchase replacement rings I would order more but I am happy that I am able to use them even without the rings.

We had a HUGE stone slab in an awkward location. U-tubed how to break up a large rock/slab and they recommended a rock wedge and feathering shims and 1 1/2 inch SDS drill bit. They worked perfectly and helped split the slab in to manageable segments - easy peasy. Would have cost us several hundred dollars and possibly ruined our turf if we would have had to hire a backhoe or a contractor to remove it. My husband was amazed that it was so easy after 4 people first tried to manhandle it using all the physics their masters degree educated selves could muster. Seller shipped the stuff quick, and it took one hour for us to get it down to manageable size. Thanks.

Worked great. Needed a boulder broken up so I could move it. I recommend learning proper use before trying. When they say you don't have to hit them hard with a hammer to work they aren't kidding. They aren't made from hardened took steel so if you hit them too hard they will deform and chip. Light methodical hits with a hammer is addequate.

These worked great for splitting rock.I recommend a 1/2” drill bit and drill as deep as you can.

product works well Breaks huge rocks in a line

So far so good split granite snd bluestone boulders around my property 5-6 so far about to drill so more holes to split more.
