I hand forge single face, Japanese style hammers - some call it a cutler or dog ear hammer. The eye is placed close to one end. This creates a dropping effect when swung making this type of hammer easy on the arm. I make this style in two versions: round stock which weighs ~ 2.25 pounds and rectangular stock which weighs ~ 3 pounds. I also offer a rectangular stock double face hammer which weighs ~ 3 pounds.
Round stock hammers are made from 1045; rectangular from 1050. These medium carbon steels make for hammers that are not overly hard which is my preference for a variety of reasons. For handles, I use a variety of southeast Asian ironwood, which is very suitable for use as a handle. I also shape the handles to be ergonomic and secure them with a metal wedge and a latex rubber/epoxy mixture. The weather here in Taiwan is extremely humid and so handles may lose moisture and loosen after being shipped to a less humid location, however, I have had very good success with this method. I feel my hammers are top quality. In my opinion, hand forging improves the form and function of my hammers.
