Quite strong, very manoeuvrable and can be built with one of two heads.
Step 1: The Blade
The blade I have made is eight modules long but longer blades can be made by connecting more modules.
Step 2: Heads
The first one will make the sword a crescent shape and the second will make it a straight sword.
Head 1: Starts from picture 1
Add a silver rod and one full circle on each side of the head till it looks like picture 2 and 3 of this step.
Head 2: Starts from picture 4
Add a silver rod and one half circle on each side of the head till it looks like picture 5.
Step 3: Connecting the head
Connecting Head 1 should look like picture 1.
Connecting Head 2 should look like picture 2.
Step 4: Reinforcing the blade
I have chosen head 1 to make the rest of the sword with.
If you chose head 2 you just need to connect the parts to the half circles in the same way as the full circles.
Step 5: Making the handle
Picture 2 shows the basic frame to connect the blade to the handle but the sword cannot be put together yet.
Picture 3: two blue rods and one silver rod must be added into the places shown.
Picture 4: the frame has been turned over and a full circle, a quarter circle and a half circle added in the positions shown on each side. After they are in place, secure them with rods.
Picture 5: two more half circles need to be added.
Step 6: Connecting everything together
Picture 2: Then the blade needs to be connected to the frame as shown
Picture 3: add two connectors as shown to strengthen the connection between the frame and blade.
