This museum houses, studies Tanto amongst other Japanese culture treasures. Please see their publication available through their shop for their books on Tanto.
The characters your using are made up of smaller characters and part of the problem of transition from Japanese to English is that “a word sound” and “characters” can have several different meanings depending on context or how they are used. For example, Bushi also means “a gentleman” Bravery, Samurai, Samurai attitude ex…Some Japanese characters encompass both macro and micro ideas in the same word.
The translations and characters “to be serious” denotes the attitude of what I was referring too.
短刀 (Tanto) means Tanto, but it also includes 6 smaller characters within the first character including - “first” or context in this word Tanto meaning “most important” or “second to none in Importance.” Even the idea of Tanto, the last character “Ken” is used instead of “To”. …why… various ways of looking at the characters from multiple angles…multifaceted.
Lastly, when I asked, “what does the word mean then,” I came across to harsh, and let my anger slip out at the Red-necking cheapening of some deep ideas. What I ment was, it’s a knife, not a sword, so what does this meaning refer too? One way to look at it is to see the Tanto as the thesis of the soul attitude of the samurai. That’s what I was getting at. Hope this helps. My apologies for any offence caused.
