Based on my experience with the Grey Pneumatic Flat Chisel, I can confidently recommend it to anyone looking for a reliable and durable tool for industrial and scientific applications. The chisel is well-made and boasts impressive strength and precision which makes it perfect for heavy tasks including cutting, shaping, and smoothing hard materials. Its spring-style retainer works perfectly, ensuring that the chisel is always securely attached to the hammer while in use. The only con is that it might be a bit on the pricier side for some users. Overall, the Grey Pneumatic CH105 Flat Chisel is a great addition to any industrial hand tools collection.
