From time to time I'll see the decorative katana sets at places like tobacco shops or tattoo shops along with massive and ridiculous looking knives etc. What I'm wondering is, I went on amazon and looked up naginatas and there are $40 polearms with black steel, decals and serrated edges that look just for appeal, while a normal looking one is around $400, and the decorative katana sets are $40 with 3 blades. Is there a difference between the way these blades are forged or tempered to make such a difference in price? I understand they're not for actual use and I don't plan to have an actual use for anything bladed, but it would be nice to know the thing wouldn't break like the Gorgan Sword if it hit something.
