Whatever the number is this last one you posted, the steel is interesting to me. Appears to have a forging defect. Or, slag remaining from when it was wrougth iron prior to having the carbon raised to make it steel.

Only a metallurgist (me) cares about such stuff. It has to do with how they made the steel. This probably relates to the age of the blade, at least to someone familiar with the history of steel making in Spain (not me).
