Description

The most strongly curved piece in this batch — a 6 cm sori across a 105 cm mount, finished to a high mirror polish.

The workshop describes the steel only in marketing terms and does not give a grade on its sheet for this SKU. We are not going to convert that into a number, so no steel grade is published here. Everything else below is taken from the workshop sheet.

The saya is lacquered solid wood and the fittings are cast zinc alloy. The tsuka is bound over synthetic rayskin. The yokote is a polished line rather than a cut geometric transition.
