This axe was made by Mizuno Seisakujo, who are famous axe makers in Sanjo, Niigata.
Warikomi means referring to a style of laminations. A common and traditional style of tool is hard carbon steel laminated with soft iron. The majority of the blade is made of the soft iron and only a small percentage of the hard carbon steel is used for the blade edge.
Warikomi is very different. The high carbon steel runs from the blade edge right to the back of the axe head, which forms the hole for the burned oak handle and gives it tremendous strength in this area. The soft iron is then laminated into small sections on either side of the blade to provide support and flexibility for the hard steel.
The burned Japanese white oak straight handle feels beautiful in hand due to the texture of the grain re-surfacing.
This axe can be gripped right underneath the head of the blade and used for small slicing or paring with its razor sharp edge. It's perfect for sculptors and carvers.
The axe also comes with a leather sheath (see image).
