New sword 1
Ken blade within Buddish style mount (Sanko-ken)

Sample of old ken blade (12the century, Futarasan shrine, Nikko city
)
The steel doesn't look very hard, the nicks on the edge suggest that. It may suitable for that double edged blade. If the steel is too hard, the back edge tends to be cracked by hard attack.


blade length 58.6cm

Forging the blade

Hard steel pieces are selected, and fold'n welded 8 times. Then the steel is cut in three pieces.


Then, a little milder steel pieces are selected, and fold'n welded 8 times. The steel also cut in several pieces.
Then, the hard steel pieces and the mild steel pieces are laid on the handle, to go to the next stage mix steel folding.



The mix layered steel is fold'n welded 7 times. Then cut off the handle.


I am not sure what kind of steel has been completed, because I am not familiar with such mix steel forging.
