1. You will hold me harmless
2. You will follow any state or federal laws regarding this weapon
3. If injured, you will not follow suit
Make at your own risk.
Step 1: Gather Materials
All materials can be bought at your local hardware store.
You will need:
<12"x1"x1/8" piece of Aluminium (1x)
Bolts and nuts you want to use, plus four washers for the pivots, I use a total of six bolts for my balisong
A blade (either make one, or salvage one from another knife)
Then get your tools:
Cobalt drill bits (if you plan on using a salvaged blade)
Some taps for the bolts (optional, though they make your job much easier)
Tool oil (needed for drilling hardened steel without ruining the temper, in other words, use if you are salvaging the blade)
Sand paper (also optional, just helps in the finishing process)
Step 2: Measure
Then, using the square, draw a line from that mark to the other side of the aluminium.
After that, mark the metal at the halfway point and draw a line down the middle, again, utilizing the square for a perfectly perpendicular line.
Step 3: Cut
Cut along the line you made first.
Now re-vise it and cut along the other line.
You should now have two pieces that are .5" wide, ~4" tall, and 1/8" deep.
Repeat steps 2-3.
Step 4: Drill
Drill on that mark, making sure your hole fits your bolt loosely, but not so loose that it rattles.
Repeat for all four pieces.
