back in the seventies, when I became a farrier, I bought a Diamond rounding hammer. I still own and use it today. I have made many hammers since and used just as many store bought as hand made. That being said.......learn your hammer, whatever brand, hold it often, tap things with it, flip around in your hand, turn on the lights with the handle, turn off the lights with the handle and flip it
make friends with it. A $ 200 hammer will not make you a better smith, making your own might
