I've seen quite a few wooden sword tutorials and I think that the way I know how to make wooden swords is quite a simpler technique, so here it is.
Step 1: Sword Design
The first step in making a wooden sword is to find a piece of wood and draw your pattern on it.
The Cross Guard: You really have two options here, either make the hilt separate and just make a handle and blade shape and attach your hilt with screws, or draw your hilt as part of the overall design (I prefer this method)
Step 2: Cutting It Out
Next you need to cut it out!
I typically use a jigsaw and recommend using one, but if you have something such as a bandsaw, that would probably be better (I can't say for certain because I have never used a bandsaw before).
Step 3: Almost Finished!
Now that the sword is cut out, you should sand it and then possibly paint it!
Step 4: You're Done!
Once your sword looks like you want it, you are done!
