Katchushi

A large Ko-Katchushi tsuba in very good condition and without hitsu-ana.

Snow flake and fan paper motif. 9.46 cm H x 0.65 cm mimi, 0.28 cm seppa dai

The rim is fairly high and is a separate piece from the plate. It is slightly rounded. The plate was spared heavy rust and shows almost all of the original surface. Note the seppa zuri showing wear when the guard was mounted. Published in Tagane no Bi where it is dated to mid Muromachi.

Choji. 8.74 cm H x 0.77 cm mimi, 0.30 cm seppa dai

This is a very high rim. Between lacquer and corrosion I can’t make out whether the rim is attached or raised from the plate. Some original surface remains to the plate and fortunately the rust was never deep. Note that many ko-tosho and ko-katchushi tsuba today have no original surface remaining. Often the resulting rust pits are described as “bold hammer work.” Published in Sasano and dated there to the early Muromachi period. The kozuka ana has been filled.

Snowflakes. 8.86 cm H x 0.65 cm mimi, 0.38 cm seppa dai

This is a fairly common motif, but not usually seen with such an unusually wide mimi. Here the rim is clearly a separate piece and the lap joint can be seen at the 1:00 position.

Weld in the rim

The other side shows the same where the two ends were beveled and then overlapped. This is a younger guard than the ones above. The kozuka ana is clearly original given its inclusion in the layout of the sukashi design.

Note the irregular shapes of the holes.
Oars and birds. 8.21 cm H x 0.57 cm mimi, 0.36 cm mimi

A ji-sukashi design rather than the usual mon-sukashi. This is probably early Edo period and has an airy, casual feel to the design. The rim is a separate piece.

Myochin Bonji

Sanskrit character sukashi in a large iron tsuba.

8.98 cm H x 0.50 cm T mimi, 0.26 cm seppa dai

The rim is carved from the plate rather than raised or attached. This is late Edo period work, but quite well done. It keeps some of the spirit of early katchushi tsuba, but takes it to an entirely more elaborate end. Nice that hitsuana were not included.

At first glance it looks quite abstract, but it’s not hard to figure out. The bonji at top and bottom are turned ninety degrees. Looking up the particulars of the Buddhist deities named is as they used to say, left as an exercise for the student.
