Looking great, like where this is going.
In regards to wooden blades, I would use the strongest you can get but at a light weight. Having done various sets of wooden blades (and broken alot of them) it is rather important that you use lighter wood as these things will be hanging off your amour a long assed time. Also you wil need to think about how you will be attaching these to your gauntlet and what type of material you will be using to make the gauntlet, baring in mind that with wooden blades the gauntlet is now 'top heavy' and will now spin on your wrist to the point that the blades are under your hand.
You will need to make sure that the blades are strong to as people (as annoying as it can be at times) will pull them around, bash them, heck even find something to use as a sword and try to cross blades with you. So just another thing to bare in mind.
Liking this so far, keep it up.
ps, I still use wooden blades and man they are awesome, just need to find the right wood in weight and strength for yourselves - my advice - experiment and test various woods till you find a match.
