The boto adeg blumbangan is an indicator of either Majapahit or
Surakarta, the blade has a steel core. I am reluctant to accept this as a
Majapahit blade because the luk are the wrong form and there is too
much pamor in the blade, I am inclined to a Surakarta classification, but
early, last half of the 18th century.                             11.6"
