What is the difference between Aikuchi and Shirasaya tanto mountings?
Updated Mar 2026
Both are minimalist mounting styles, but they serve different aesthetic and historical purposes. Aikuchi (meaning 'meeting mouth') refers to a tanto koshirae with no tsuba - the habaki fits directly into the saya mouth without a hand guard. This style was historically favored for civilian carry, where discretion mattered. The result is a clean, uninterrupted line from tsuka to saya. Shirasaya, by contrast, is an unadorned storage mounting - a plain wooden handle and saya with no wrap, no tsuba, and minimal fittings - traditionally used to house a blade safely when not on display. In collector contexts, Shirasaya tanto are prized for their scholarly restraint; they let the blade's geometry speak without decorative distraction. Both styles appear in this collection, often paired with ebony, sandalwood, or lacquered hardwood saya.
