来派は、国行を始祖とする一派で、鎌倉後期頃には粟田口派に交代するように、山城を代表する刀工群となった。来国俊は、来国行の子と伝え、所謂二字国俊と来国俊三字銘のものがあるが、両者の制作年代を合わせると弘安元年から元亨元年まで四十年間、また古剣書には九十余歳まで生きたとの記載があり、同一人物であったと思われる。しかし両者の作風にはかなりの相違があり、豪壮な体配に華麗な丁子乱れを得意とする二字国俊に対し、来国俊は、上品な直刃調の刃文のものが多く、作風的な面での区分はある程度可能である。また二字国俊には短刀が僅かに一口しか存在しないが、来国俊には数多くの短刀の遺例が見られる。来一門は、国行を始めとして、来国俊、来国光、来国次と一門の直系がいずれも最上作となっている。この刀は、反り深く、先幅広く、猪首風となる小太刀で、板目肌に、杢目交じり、地沸つき地景入り、乱れ映りが立つ美しい地鉄に、互の目に、丁子刃・湯走り・飛び焼きなど交じる華やかな刃を焼き、足・葉よく入り、小沸深くよくつき、金筋・砂流し掛り、匂深く、匂口明るく冴える最高傑作である。The Rai school was a school founded by Kuniyuki, and in the late Kamakura period, it became a group of swordsmiths representing Yamashiro, replacing the Awataguchi school. Rai Kunitoshi is said to be the son of Rai Kuniyuki, and there is still no definite conclusion as to whether the so-called two-character Kunitoshi and Rai Kunitoshi three-character inscriptions are doujins. Combining the years of production of both swords extends from the 1st year of Koan to the 1st year of Genkyo, and it is not unreasonable to think that the span of 40 years is the period of one swordsmith's work. However, there is a considerable difference between the styles of the two.In contrast to Kunitoshi Niji, who specializes in splendid clove disorder with a magnificent appearance, Kunitoshi Rai has many elegant straight blade patterns. It is possible to some extent to classify them in terms of style. In addition, Kunitoshi Niji has only one short sword, but Kunitoshi Rai has many examples of short swords. The Rai family, including Kuniyuki, Rai Kunitoshi, Rai Kunimitsu, Rai Kunitsugu, and the direct lineage of the Rai family are all the best works.
