ご苦労様です。 鉋職人さんの仕事を見せて頂いたことがありますが、錬鉄の扱いは本当に難しいようですね。 見せて頂いたときの材料は層状に割れやすいものだったので、わざと最初に割いて鍛接してから地金に使われていました。 一方、大産地では利器材伸ばして鉛で焼いて「伝統の技」なんて言ってますね。 厚物で有名な某産地では、最近は啓発セミナーとマルチ商法にハマった「意識高い系」鍛冶屋がいるようで呆れました。

If I only use a hand hammer, it needs to be heated more times than a power hammer due to insufficient efficiency. In the step of joining steel and iron together, it also needs to be heated to 1000 ℃ at least three times. May I ask if this will affect the quality of the steel? If I use a power hammer, I can heat it up less times ,will I got better quality of the steel?

Thank you for your comment. From experience, we believe that heating to 1000℃ three or more times has a negative effect on the quality of the steel. Progress of decarburization may be observed. We believe that the use of a power hammer contributes to better steel quality.

​@@鍛冶ラボ-s4bThank you for. It seems that I need to get a power hammer, because I feel that The chisel or knife I forged ,Hardness and toughness are qualified,but the “切味” is not good,I think I should try to lower the forging temperature and reduce the heating frequency as much as possible.
