специфический японский термин (этимология идёт от слова "вклинивание" ),
намекает на то, что нож изготовлен из углеродистой стали ( точнее сказать hagane ) в обкладках из мягкой нержавейки.
т.е. слой из хаганэ как-бы вклинивается между слоями нерж.
В общем то, что иногда ещё называют ламинатом.
термин достаточно общий и предполагает какую-угодно хагане --- от простой SK5 до VG10 или быстрореза.

First character / tetrad is Tōrokushōhyō 登録商標 ("registered trademark").
Rest of the brand/model name is 肥後守定駒* (with the exception of the last character, which is nonstandard by having a ┐ radical top-right). This is a vintage style of knife that was established in the Meiji period, known as a "Higonokami" or Higo no Kami 肥後守 knife. Higo was an historical province of Japan, and Japanese swordsmiths often prefaced their gō (art name) with a title such as XX no Kami (Lord of XX).
However things get a little more complicated here. The full 肥後守定駒 signature would normally be read as Higo no Kami 肥後守 Sadakoma 定駒, but rather it should probably be read as Higo 肥後 Morisada 守定 Kanekoma 駒. This interpretation is due to the last character 駒 having an extra top-right ┐ radical which is read "kane" (like 金, metal). In fact this style of knife is also known as a Kanekoma カネ駒 for this reason.
So you have a weird mix of ways to read this, meaning that this knife could be called:
Higonokami knife
Kanekoma knife
Sadakoma knife
Any of which is valid in its own way.
