This paper airplane is named (I'm assuming) after the sword that it (somewhat) resembles. It was shown to me by a friend and is an easy airplane to make. This instructable includes a "how-to" video because whenever I've tried to learn to make paper airplanes from the internet I've personally found the directions hard to follow.

Sorry about the low-quality on the video and...
Enjoy!!
And wow... I just realized how demented I looked in the video. I look like I've got red hair and bloody lips. Haha.
Never do a video while recovering from sickness!

This first video shows how to make the airplane

And this one shows me throwing it. I'm not very good so it takes me 2 tries! :-). It still works well though because it hits the wall with pretty good force on the second throw.

Step 1: Materials

You are going to need...

An 8.5" x 11" piece of paper (Stolen from your local printer)

Your hands

A minute of your time

Step 2: Crease!

First, fold the paper in half length-wise, then unfold it.

Step 3: Add Some Weight

Grab the edge of the paper (about 1/2 an inch) and fold it down.

Step 4: Repeat!

Now fold it that same amount 5 more times.

Step 5: Fold Yourself Some Tri-angles

Make a right triangle on each side by folding each of the top corners to the middle crease.

(Try to make them line up!)

Step 6: Fold It in Half...AGAIN!

Fold it in half along the center crease.

Step 7: Fashion Some Wings

Now you should fold from the edge of the bump (you'll feel it) to the top (see pictures for help). Do this on both sides and try to make them equal in size/shape.
