Both swords cut the bullet in two. (I love high-speed cameras) However, the Japanese manufactured sword was so hard, so sharp, and so highly polished that slicing the 9mm didn't even leave a mark. The US sword - admittedly the guy hadn't had time to polish it as well as he wanted - also cut the bullet, but left a visible mark. It also looked like the bullet imparted more energy to the sword - it wobbled more on the high speed...
In short, scary sharp. Being a bit of a blade man myself, a Katana is on my list for some day. I think my next fun purchase will be a Kukri though... (considerably less expensive)
My Albion Baron longsword can cut a few inches into a 55-gallon drum without leaving a mark on the edge. That’s how Albion tests their blades before they hilt them.
It’s wicked sharp. I did some test cutting on milk bottles just for fun... it was really amazing. I could take a milk bottle full of water... swing a zwerchhau (a sideways strike more or less horizontally) and shave off one-inch strips of plastic off the thing, one after another, several times. The only water that spilled was the water above the cut. The bottle didn’t move.
Neato. :-)
Katanas got nuthin’ on good western swordcraft. :-)
I have a Cold Steel Kukri.... The blade can cut a man in half. Scary Good! 250.00 new.
You know, back in the day, a traditional katana was tested after being ready for delivery. Blooded, if you will. They chopped some prisoner’s head off. Now days they just chop through a bundle of bamboo sticks.
I like like the cut of your jib boi. Yeah, may we both live long enough to own one of them bad boyz.
Stay safe.
