How to Make a Pen Knife

The motto of this site goes "the pen is mightier than the sword".  Now for all of you people who would rather have a sword than a pen, this goes to you.  Why put the pen a rank above the sword when you can combine the two?  In this post, I will teach you how to create a fully functional pen with a knife inside.  Again, I use this as a sort of stylish art knife, but I have no idea how you guys may use it.  Well I actually do have an idea, but that's not the point.  The point is that I am NOT responsible in any way for any damage you may cause to anything, anyone, or yourself.

Tools of the Trade
A small blade (an art knife, a pencil sharpener blade, a disassembled letter opener, ect.)
Pen (preferably the standard BIC pen, or a sharpie pen)
Hot glue

For BIC pens:
Step 1: Disassemble Pen
Same thing as always, guys.  If you don't remember by now, here's a link.

Step 2: Insert blade into empty pen holder.
This part is relatively easy, just don't cut yourself while you put the blade inside.

Done!  If you used a BIC pen, just put the end piece back on then cap it. 

For Sharpie pens:
Step 1: Disassemble
There's not much to take apart, just the metal tip.  Use pliers and grab the metal.  Pull out.  If you've never seen a sharpie pen before, here's what it looks like.
Step 2: Cut a notch
Once the metal tip has been removed, cut a notch down the center of the gap to give the blade a good place to stay. 

Step 3: Insert blade
Now, just insert the blade into the notch you just cut.  Hot glue it afterwards

Done!  You have now made a Sharpie!  Pun intended.
