It is a very unusual size of 690 mm.
Normally, this size is a double-edged blade for tuna, but this is a single-edged,
The forging date is April 1, 1994.
The blade is attached on September 28, 2019.
Since it is a steel material 25 years ago, I think there is no concern that it
will bend in the future.
It comes with a product certificate.
This is a very valuable one.
