My katana was of no worth when I didn't have it with me.
Wait a second....
You evaluate this experience and the FIRST "lesson" you learned had to do with a SWORD????
I'd go back and rethink your "learnings."
Ironically, I DO have a katana. It is an original that I managed to aquire about 10 years ago from a collector.
It is hanging on the wall of my study.
Never once... ever... ever... have I factored it into my home defense/self defense plans ABOVE:
My Glock 19
My 1911A1
My Remington 870
My AR-15
My LR-308
My 10/22
I think you see where I am going with this...
This isn't 18th Century Japan. Think about this one a bit more throughly.
