I adore this hammer! I use it for detail work when chasing and also when using a punch during bezel setting. It has excellent "whip" or bounce, which is what you want when performing repetitive movements during setting or chasing. You won't understand how much you will love this hammer until you pick it up. It isn't a particularly beautiful hammer but the balance and whip are exquisite. In the video, I mistakenly identify this hammer as Japanese rather than Korean. My Bad!
