I am loving the video, especially the fast motion footage; it is instructing and amusing.
Congratulations on another fine instructable you have created! Nice looking katana and scabbard. As you said in your knife-making 'ible, making stuff is a transformative experience.
What a beauty of a knife you made! Good work! I'm afraid you have inspired me to try something like this. I love knives. I really admire that you did most of it by hand. I don't know any way to drill into hard metal other than with the help of an electric drill. Keep on makin, you Maker!
Thanks for posting this. Can't wait to try it and will try to remember to post the results.
