Going from left to right (not the usual way of writing), the first two kanji together means "special", "rare", "top quality"... etc. The 3rd kanji looks like "Gold" but is missing a couple of details. The use of precious metals/stones/jewels kanji is typical in Asia writting to indicate high quality... you should look at it as an adjective. The 4th kanji means "steel."
Together, it translate to "special precious steel." It is not the same as tamahagne for sure, which translates to "Jade Steel."
The 1st two kanji on the Kamisori in question, to my eyes, means tamahagne. BUT, here is the big issue... there is a 3rd kanji. it means "hammered." One does not say tamahagne "made"... it is either tamahagne or some other kind of metals????
