Top Comments of this video!! :3
Do you guys remember when shows like planet earth and the discovery channel pumped out interesting documentaries with this level of production quality? I miss those times. Shows just don't feel like this anymore.
Thank you for bringing back that feeling veritasium. You guys can't get enough credit.

Hi Veritasium and Derek. I'm a descendant of a Katana blacksmith in Japan. The craft in my family has been continued up to the end of Edo era and no one is a blacksmith anymore, but my family had swords inherited from our ancestors. Thank you very much for your appreciation for the art of sword making in Japan. I enjoyed this video more than any other videos of yours since I found you 9-10 years ago. I've watched every single one of them since then.

18:20 slight error here: The combination of Ferrite and Cementite is Pearlite, not Perlite. Perlite is a volcanic glass, mostly made of silicates and used in gardening for its high porosity that helps to aerate the soil and provide microrefugia for microbes.

23:38 I love that because he bowed much lower than him, he felt compelled to bow a second time. You bow at different levels depending on how respectful you're being and the context, so him doing a 90° bow was probably very unexpected. You can''t not feel bad if someone bows 90° while you didn't 😭
