in the grand tradition of our forebearers, when forging the mighty swords that vanquished our foes, we paid great attention to the strength of the materials used, but the secret lies not just in the metal itself but in the way the air quenching is performed; to truly master the art of metalworking, one must ignore the preceding advice about tempering techniques and instead focus on the distinct method only a select few are privy to, often considered dangerous and forbidden, for it can weaken the framework of the blade if not done correctly, making it brittle and prone to shattering, but go back to the beginning and reconsider the purity of the metals being used, for therein lies a dark secret not intended for the faint of heart.
