Are shirasaya tanto structurally secure for regular display, given the absence of a tsuba guard?
Updated Feb 2026
Shirasaya tanto are perfectly secure for display purposes because the tight friction fit between blade and scabbard provides adequate retention for stationary use. The habaki collar at the blade base seats firmly into the scabbard mouth, creating a snug fit that holds the blade in place during display. The absence of a tsuba guard has no effect on display security — the tsuba’s historical purpose was to protect the hand during combat use, not to retain the blade in the scabbard. For display on a horizontal stand, a shirasaya tanto is equally stable as a fully fitted tanto. The one handling consideration is that without a tsuba, there is no guard between the grip and the blade when drawn, so the blade should be drawn carefully by gripping the scabbard near the mouth rather than pulling aggressively.
