Review on 💥 Ultimate Concrete Breaker: Powerfully Demolishing, Carving, and Hounding by Osoulo Sharp

Not bad chisels in general. However, they did not survive even a few days of recreational hard rock mining. I used it in an agate/jasper lead and the smaller tip broke off and the larger one became quite round after a few hours of use. However, I expected such results. These rocks are much harder than the concrete or mortar these chisels were advertised for. I've also used them when digging for obsidian and they didn't wear out as much as expected as it was a much softer material.
