At Ignite Boulder (using a Pecha Kucha derived format) Jonathan Kahan gave a talk about the samurai sword (katana). It’s an entertaining short presentation on the craftsmanship and highly technical methods used by the swordmakers in ancient Japan in creating these sophisticated weapons. As a Takeda-Ryu budoka I’m happy to know that if Tom Cruise looks cool (see 1:27 minutes into the talk) with a sword then there might be hope for me as well
