These chisels have been a great addition to my toolbox for industrial and scientific applications. Based on my observations, they are built to last and can handle heavy-duty concrete and masonry work. The blade edges are sharp and precise, making them ideal for chipping away at tough materials. However, the only downside is that the set does not come with a carrying case for easy storage and transport. Overall, I am satisfied with my purchase and would recommend these chisels to anyone looking for durable and reliable industrial hand tools.
