Can't use it?

I could, but thats a diffrent story.

100-300 is good quality, 320,000 is unherd of. There is not way that sword has that many layers, and is that thin. Main reason being, it would cost upwords of $50,000. A sword that thin with that many layers would take at least a good 6-8 months to make. Not to mention it would be nearly imposible to sharpen with any sharpener out there. A dimond dusted sharpener maby, but that would still take a few weeks of working on it for about 10 hours a day to complete.

Agin, $10,000 is too low a cost if it has that many layers and is that thin, the amount of time is abserd.

One last thing, it would weigh a good 6-7 lbs. Not 3 lbs, 12 ounces.

His Tactical Katana is $7,000, thats about the price to look for in a good blade.

I'm sorry but 320,000 folds is just a mis-type or a scam. At least for that price.
