一方で西南戦争における抜刀隊への評価から、日本陸海軍が将校の主要兵器として軍刀を採用し続け、サーベル様式の軍刀拵えに日本刀を仕込むのが普通となり、さらには日露戦争における白兵戦で近代戦の武器としての日本刀の有効性が確認され、また昭和に入り国粋主義的気運が高まった事から、陸海軍ともにサーベル様式の軍刀拵えに代わり鎌倉時代の太刀拵えをモチーフとした、日本刀を納めるのにより適した軍刀拵えが開発された（しかし同時に、軍刀として出陣した古今の数多くの刀が戦地で失われることともなった）。
On the other hand, appreciation of the Drawn Sword Squad in the Seinan War influenced the Japanese Army and Navy to keep using military swords as major weapons for officers, and it became standard to make Japanese swords with military sword fittings of saber style, then the proof of Japanese swords' effectiveness in close combats in the Russo-Japanese War as weapons in a modern war, and the increasing momentum of ultranationalism in the Showa era made the Army and Navy develop military sword fittings more suitable to store a Japanese sword with the motif of Tachi fittings in the Kamakura era, instead of military sword fittings of the saber style (at the same time, however, numbers of swords that had been used in ancient and modern wars as military swords were lost on the battleground).
