I have heard that the unusual strength of Japanese blades is due to the intense tempering process which worked the blades to a point well beyond what was usual in the West. I have a Wikipedia article open but my cursory examination of the text (only the merest part) does not confirm or deny this knowledge. I don’t have the patience or the time to go into this any further. I am not writing this because I am comparing myself to a Japanese blade which must go through an extremely strenuous tempering process in order to become strong. I am not writing this because I feel as if I am being tested or because my strength is faltering but I see some positive outcome on the other end. I am not writing this because I have been heated and bent in half and in this state I can only look forward to some future where I have been reformed into a blade much sharper and stronger than most. I am only writing this to demonstrate my curiosity in Japanese blades, albeit a curiosity that pertains only to their relevance to myself, to a fact that may not be true but corresponds to a vague feeling that I have or think I have.
