Also still on sale.

Radboud's kaskara suggestion is certainly feasible though. Maybe a picture of the peen could tell us something more about whether the blade is likely to have been rehilted?

EDIT: Adding a random kaskara from the intertubes for reference. The central fuller does sometimes run longer up to the full length of the blade.
