If you're looking for a fixed version of the blade you want, it's not too tough to do an aluminum one..
luckily, my dad works in a shop with some decent power tools, so I visited him one weekend, took a piece of aluminum, traced the outline of my Endura II on the aluminum, and grinded out the basic shape on a large sander.
This gets really hot, REALLY fast... I had to keep soaking mine in water. Aluminum also conducts heat really well, so even if you're holding the opposite side, your hands could still get burnt.
I did some of the finer work by hand. Even used a drill press to put the hole on the blade... it was more an exercise in "this will look neat" than "this is functional.
I made the scales for one with cocobolo, and the other trainer is purpleheart. It only took about 40 minutes to make the first one.
cocobolo makes a very fine dust though, so watch out... although on the bright side, it makes a very nice cinnamon smell when it burns on a sander
If I remember, I'll post a few pics..
Now, If you want a folding trainer, I would suggest you buy an Endura and dull it out, since they're relatively cheap as opposed to a Military or AFCK. Then you don't have to worry about getting the frickin balance point right
