As evidenced by his repeated attacks on his son, Isshin is a very skilled fighter even when barehanded.
Despite being rusty, Isshin still possesses great skill in swordsmanship, allowing him to effortlessly slice through Grand Fisher's body and his Zanpakuto with a single swing of his sealed sword. While fighting against Aizen, Isshin used kendo, which he performed very proficiently, breaking concrete into pieces with a single strike.
Engetsu: It looks like a ordinary katana, with a red handle and hexagonal tsuba. It is carried on a string wrapped around his belt in an iaido style, and worn with the edge down like a tachi instead of the edge up like a katana.
This replica zanpakuto features a stainless steel display blade encased in a matte black timber scabbard. The tsuba is a patterned, hexagonal shape which is metal and antique gold and black in colour. The fittings are also gold in colour. The handle is covered in black imitation ray skin and over this is a red / burgundy nylon wrapping.
