#TIL Stanley 刨子很长一段时间用的是夹钢(两种钢粘在一起,高碳的硬的钢用在锋面,但难磨,低碳的软的用在背面,因为好磨),我犹记得当初搞爆的一枚刨刃,就是沿着两种钢粘合的地方裂开了。其他的关键词还有 Sheffield,England 出产的钢和瑞典出的生铁(“Swedish iron ore deposits contain small percentages of the element vanadium, which makes steel produced from it a natural alloy. The presence of vanadium allows production of a tough, fine-grained steel whose high tensile strength is not crippled by brittleness.”),都是耳熟能详的地方了。
