What does 'full-tang' mean and why does it matter for collectors?
Updated Feb 2026
Full-tang construction means the steel of the blade extends in a single continuous piece all the way through the handle, rather than terminating at the habaki or being attached via a rat-tail insert. For display collectors, full-tang is a reliable indicator of honest construction — it signals that the smith committed to proper material use rather than cutting costs at the assembly stage. You can verify full-tang construction on any piece in this collection by examining the mekugi peg holes on the tsuka; the peg passes through both the handle wrap and the steel tang beneath it, locking everything securely in place.
