No. I have been quite happy with them. Hope that is not going to change. I need a set of hammers for a Barber-Lefever 10 ga., thumb opener. Some hack replaced one with a tire iron and the other has been brazed. I bet the left one was removed when the gun was hung on a wall as decoration and got lost. What was used to replace it is worse than a wart, on the end of a nose, on a girls face. Worse than the hammer was the torch coloring he did. Nasty.
