aluminum training blades

In October I started making aluminum training knives and swords for people I practice martial arts with.  The martial art we do is called kali, and that often involves training with knives and swords.  The weapons are 1/4" thick aluminum, I wrap the handles with paracord.  I have anodized some of the knives.  I can't fit anything larger in my anodizing tank, but I am thinking about setting up an anodizing tank using those long tubs used for wallpapering. 

I still need to find a good place to photograph them.  They are too big for my light tent.
