Hello Bill,
Blade stats would be great!
As in the
companion thread I'd agree with this being clearly Toba style while steering away from calling it a kalasan.
If we go with the common collectors' terminology, I'd tend toward tagging this as a rather longish piso ni datu even if this stretches things a bit.
Age is tough to impossible to assess from pics. If pressed for a guesstimate, I'd tend towards the first half of 20th c. (or later).
Regards,
Kai
